ANNOTATWE [/DA/

Add annotation to the plot, or remove any existing annotation. The text

required (up to 10 lines) is first requested, and then the required position of

the top left of the first line of the text is selected by using the cursor. Any

set of lines already on the screen (for the current Bench and Blast) will be

replaced if a notional box surrounding the new text lines overlaps with a

notional box surrounding the old lines. The lines of text entered by the

ANNOTATE [/DA] command will be treated as a unit. All text lines are held

on the &TEXT file. The size of the text characters is controlled by the

current character size: this may be changed by the DEFAULTS [/CF]

command. The text character size is expanded or contracted if the picture

is ZOomed after the text has been placed. All text lines are always plotted

horizontally w.r.t. the current screen X axis.

ANNOTATION

---------------------------------------

Enter up to ten consecutive lines of annotation to be shown together on the screen. End with a blank line. ! to terminate, < to re-start lines.

> Enter text line.

When ten lines (or a blank line) have been entered:

>>> COORDS OF TOP LEFT OF FIRST LINE <<<

>>> DEFINE START POINT OF TEXT WITH CURSOR <<<

Use F1 key or mouse button to select the required position.

If within a macro, prompts replace the cursor selection:

>X COORDINATE > Enter screen (mm) position in X.

>Y COORDINATE > Enter screen (mm) position in Y.

CH

CUT HOLES IN PERIM [/DC] 

Cut holes inside or outside the current perimeter. If no current perimeter is defined, the Blast outline is used.

Delete holes inside (I) or outside [O] perimeter ?

>[O]/I >

Enter <return> to cut (delete) all holes outside the perimeter; I<return> to delete all holes inside the perimeter.

The display is refreshed if any holes have been deleted.

CP

CONSTRUCT P/LINE [/??]

Construction of planimeter lines.

It may be necessary to define the Blast Outline in terms of lines at particular distances from the rows or columns of blastholes, for accuracy in volume estimation. These are the lines referred to as 'planimeter lines'. The method of use is to first define a starting current perimeter (NEW PERIMETER [/BN] command) around the edges of the blastholes.

Then the CONSTRUCT P/LINES [/??] command may be entered to move either the entire perimeter or individual line segments the required distance at right angles to the starting lines.

It is possible to re-move individual lines more than once during CP; each time, the original line is the starting point. The algorithm ensures that the end points of each moved line segment are correctly calculated as the intersection of neighboring line segments.

Lines may be moved either to the left or right of their current position, as determined by looking from the start to the end points selected. Thus, for a clockwise perimeter, left is outwards; right is inwards.

It is possible that exceptional circumstances, such as lines disappearing or

intersecting at very small angles, may cause the projection to be incorrect. The solution is either to abandon the CONSTRUCT P/LINES [/??] operation (in which case the original perimeter will be restored) or to manually edit the perimeter, within CONSTRUCT P/LINES [/??]. Manual editing is also the way of coping with exceptional cases such as ramps, when the projection distance may vary along the line.

At the end of the operation, the user may choose to replace the current blast outline with the new perimeter. Following this, the new blast outline will be used for all volume calculations. IN ORDER TO SAVE THE NEW BLAST OUTLINE PERMANENTLY TO FILE, USE THE WRITE BLAST [/FW] COMMAND IMMEDIATELY ON EXIT FROM CONSTRUCT P/LINES [/??]. If you do not do this, the outline will only remain until you get a new blast outline with the GET BLAST OUTLINE [/FB] command.

Construction of Planimeter lines

--------------------------------

For volume estimation, a new blast perimeter will be constructed from the current perimeter. The CP sub-command allows you to move all or part of the current perimeter a given distance to the right or left of the current position.

Normally the current perimeter should be drawn along the hole limits on entry to CP.

---- Select start and end of line to be moved with F1 (F2 to cancel) ----

The direction around the perimeter is always clockwise. Select the same point twice for the complete perimeter.

---- Move line to Left or Right, looking from start to end ? ----

>R/[L] >

Enter R for Right, L (or <return>) for left.

---- Enter distance to be moved [ 3.00] ---

>DISTANCE >

Enter the required distance, or just <return> to use the default. Note that the default remains at the last entered distance. Default on first use is 3.00.

The perimeter, or part perimeter, selected is moved and shown on the screen. If the new perimeter has cross-overs or is otherwise malformed, the message is produced:-

---- Warning - perimeter is malformed ----

Do you want to continue ?

>Y/[N] >

Enter Y to continue to edit the perimeter; or N or <return> to abandon the CONSTRUCT P/LINES [/??] command.

Otherwise, you may continue to move another line or set of lines, or re-move a previously moved line:-

---- Move another line (Y/[N]) (! to abort CP) ? ----

>Y/[N] >

Enter Y to re-start line selection; N or <return> to continue

---- Do you want to edit the perimeter (Y/[N]) ----

>Y/[N] >

Enter Y to edit the perimeter; N or <return> to continue

If editing the perimeter, then any of the EDIT PERIMETER [/BD] functions are available. Note however that use of any command (e.g. REDRAW [/DR]) will terminate the edit process. If the edited perimeter is malformed:-

---- Perimeter unacceptable. You may either re-edit or discard it ----

Re-edit it ?

>Y/[N] >

Enter Y to re-edit the perimeter; N or <return> to exit CONSTRUCT P/LINES [/??], discarding the perimeter.

If the perimeter was acceptable, or not edited:-

---- Replace Blast Outline with this perimeter ([Y]/N) ?

>Y/[N] >

Enter Y or <return> to accept the new perimeter as the current blast perimeter; N to just leave it as the new current perimeter.

CU

CURSOR [/CU]

Switch between cursor and keyboard input modes.

DF

DEFAULTS [/CF]

Reset default values. This command allows extra control over many of the standard methods of operation of other commands.

1) NONE. REQUESTED WHEN NEEDED

2) PERIMETER INPUT FILE

3) PERIMETER OUTPUT FILE

>OPTION > Enter 1, 2 or 3.

Note: this refers to the composite outlines. Since the same file is used for both input and output in LAYOUT, this option has no effect.

For 7:

SET PERIMETER FILENAMES

INPUT PERIMETER FILENAME

>DATAMINE FILENAME? > Enter required perimeter filename. This file must exist and be a valid perimeter file.

OUTPUT PERIMETER FILENAME

>DATAMINE FILENAME? > Enter required filename. If this exists, it will be over-written.

DH

DEFINE HOLE [/BD]

Define new holes or edit existing hole locations with the cursor.

Definition/Editing of holes with cursor:

1. add new hole at cursor location

2. delete hole nearest to cursor

3. mark two holes with cursor and insert hole midway between them.

4. mark two holes with cursor and give positions and distance between.

5. End by selecting new command with cursor.

To insert a new hole, move the cursor to the required location and press F1 (mouse button 1). The hole will be rejected if it lies on top of an existing hole.

To delete a hole, move the cursor to the vicinity of the existing hole, and press F2 (mouse button 2). The hole will be deleted; a cross will be plotted over the hole.

To insert a hole half-way between two existing holes, move the cursor to the vicinity of the first hole and press F3 (mouse button 3). Then repeat for the second hole. A new hole will be inserted half-way between the chosen holes (unless a hole already exists at this position).

To query the position of holes and the distance between them, move the cursor to the vicinity of the first hole and press F4. Then repeat for the second hole. The location of each hole and the distance between the holes will be shown on the text screen.

New holes will not have a hole identifier (BHID), and any grade fields will be set to absent data.

DI

DIGITISER [/CD]

If @DIMENU=0 (default) then the following procedure should be followed:

Digitise new line or outline. If no reference points are in force, these will be requested. End by pressing 'End of Digitisation' digitiser button.

If reference points have previously been entered:

>>> REDIGITISE REFERENCE POINTS? <<<

>CONFIRM ? > OK, ok, YES, yes, Y or y to redigitise points; <return> to continue with existing ones.

DIGITISER TRANSFORMATION COMPUTATION

If @DIMENU=1, then the DIGITISER [/CD] command becomes the switch between cursor and digitizer input mode, and the user will be asked to define the location of the digitizer menu by digitizing the left-hand, then the right-hand registration marks. The user should fix the menu securely to the digitizer before doing this. The digitizer menu may be relocated at any time the digitizer is being used. There is a small fixed "menu", usually in the lower left-hand corner of the digitizer with boxes marked "LOCATE DATAMINE MENU"; "ERASE DATAMINE MENU" and "RESTORE DATAMINE MENU". Selecting the first of these, the user will be prompted to digitize the left-hand and right-hand menu registration points again. The user may do this as often as required. Select the second of these boxes to erase temporarily the large DATAMINE menu (for example to digitize a string that runs behind the menu). Select the third of these boxes to restore the menu again. To begin digitization, choose the NEW PERIMETER [/BN] command from the digitizer menu.

DP

NEW PERIMETER [/EN]

If @DIMENU=0 (default), then this command is used to define a new line or perimeter using the screen cursor. If there is an existing line or perimeter, the points are placed in a bank and may be used as part of the new line or perimeter.

The command SNAP MODE [/EP] may be selected from within this command without exiting. This allows the use of function button F3 to either select a point from the bank (default), a point exactly on a line joining two bank points, or a segment of an existing perimeter or string. SNAP MODE [/EP] toggles between these three modes. As well as any previous perimeter, the bank points contain:-

- The blast outline.

If the DISPLAY STRINGS [/DD] command has been selected, or the PLOT CONTROL [/CL] command has been used to switch on these outlines, then in addition the bank contains:-

- All previously stored perimeters.

- Geology lines from the &GEOL file.

This command is terminated by selecting a new command with the cursor (except for SNAP MODE [/EP]).

During execution of this command, the function buttons have the following meaning:-

F1 - add a point at the current cursor location to the perimeter following the current point.

F2 - delete the current point.

F3 - add the nearest bank point to the cursor to the perimeter following the current point (if snap mode is set for points - SNAP MODE [/EP] command); or add a point which is on the line between two connected bank points (if snap mode is set for lines); or select a first point, a middle point, and an end point on an existing perimeter or string with F3 (if snap mode is set for Segments). In this last mode, the first point defines the line, the second point the direction to take, and the third point the last point required. The second and third points will only be taken on the same line as the first point.

F4 - make the perimeter point nearest the cursor the current point and identify it with a circle. Perimeters will be checked for duplicate points and cross-overs, and will be corrected (and made clockwise) if possible.

If @DIMENU=1 , then this command is used to digitise a perimeter using the cursor or digitizer depending upon the current cursor state.

DU

Screen dump to hard copy device (if available)

EH

EDIT HOLE [/BT]

Edit hole attributes. Allows holes to be selected with the cursor and their existing attributes displayed and changed. Valid only for holes in the &COLLARS file.

EP

EDIT PERIMETER [/ED]

Edit the current line or perimeter. Points may be added, deleted, or inserted. This command works in the same way as the NEW PERIMETER [/EN] command, except that the current line or perimeter is not deleted first. The current point is the last point on the line or perimeter on entry to this command.

The command SNAP MODE [/EP] may be selected from within this command without exiting. This allows the use of function button F3 to either select a point from the bank (default), a point exactly on a line joining two bank points, or a segment of an existing perimeter or string. SNAP MODE [/EP] toggles between these three modes. As well as any previous perimeter, the bank points contain:-

- The blast outline.

If the DISPLAY STRINGS [/DD] command has been selected, then in addition the bank contains:-

- Geology lines from the &GEOL file.

During execution of this command, the function buttons have the following meaning:-

F1 - add a point at the current cursor location to the perimeter following the current point.

F2 - delete the current point.

F3 - add the nearest bank point to the cursor to the perimeter following the current point (if snap mode is set for points - SNAP MODE [/EP command); or add a point which is on the line between two connected bank points (if snap mode is set for lines); or select a first point, a middle point, and an end point on an existing perimeter or string with

F3 (if snap mode is set for Segments). In this last mode, the first point defines the line, the second point the direction to take, and the third point the last point required. The second and third points will only be taken on the same line as the first point.

F4 - make the perimeter point nearest the cursor the current point and identify it with a circle. Perimeters will be checked for duplicate points and cross-overs, and will be corrected (and made clockwise) if possible.

EX

EXIT [/X]

Exit from Blast Layout.

If the blast-holes have not been saved, the prompt is:-

>>> BLAST-HOLES NOT SAVED ON FILE <<<

>>> SAVE? (Y, YES, OR OK TO SAVE) [N]<<<

>CONFIRM ?> If the response is anything other than Y, y, YES, yes, OK or ok then LAYOUT is exited.

The blast-holes will be written to the HOLES file before the process terminates.

GB

GET BLAST OUTLINE [/FB]

Gets a blast from the IN file and resets all values for processing a new blast. The required Bench and Blast number are requested; these become the current Bench and Blast and remain in force until a new GET BLAST OUTLINE [/FB] command is entered. The principal axis of the blast is determined, and the blast rotated so that this fits horizontally along the screen (or the user can specify an angle). Blast-holes may be filtered from the HOLES file through this blast into a temporary file TEMP$$$$ if required; the advantage of this is that it speeds up processing and ensures bar averaging only uses those holes within the blast. The blast is then centered on the screen and displayed. The prompts depend upon whether this is the first time that LAYOUT is entered, or whether a blast has already been chosen. In the latter case, the previous responses are remembered.

This means that a blast can be re-loaded by simply pressing return to all questions. The prompts are:-

SELECTION OF REQUIRED BLAST

--------------------------------------------------

Enter one of the following:-

? <return> for a list of all blasts on file

the required bench no,

First request:-

<return> for the first blast on the file

Subsequent requests:-

<return> for bench number 99999.9

>BENCH > Enter ? <return> for a list of all blasts; <return> to take the default; the bench number <return>.

Enter the required blast number

Subsequent requests:-

or <return> for blast number 99999.9

>BLAST > This prompt is only given if a bench number was entered previously. Enter the required blast number, or <return> for the default.

Select angle of blast for display:-

Enter <return> for default angle of 99999 degrees

Enter - for computed angle (major axis of the blast)

of 99999 degrees anticlockwise from the horizontal,or

Enter a new value (-360 to 360)

>ANGLE > Enter either <return> to accept the default figure, - for the computed angle, or the required angle (-360 to 360).

Please supply base-of-bench elevation, Enter - to take the bench number 99999 For subsequent requests:- or enter <return> to take previous base :99999.9

>Z VAL > Enter the elevation of the bottom of the bench; or - for the bench number; or <return> for the previous value. This is used to select all blast holes lying within the bench.

Please supply bench height (>0) for this bench,

For subsequent requests:-

<return> will take height of 999.9

>HEIGHT> Enter the bench height, or <return> for the same bench height as before. This is used for volume calculations and for selecting blast-holes that lie within the bench.

Do you want all blastholes for this bench, including

those outside the blast (N), or do you want to filter

blastholes inside the blast [Y] ?

>[Y]/N > Enter N to use all blastholes on file.

GH

GET HOLES [/FO]

Get all holes from file for the current Bench and Blast. This command is automatically invoked following GET BLAST OUTLINE [/FB]. If there are already holes in the working array, the message is produced:-

Previous holes not saved to file. Delete?

>[N]/Y > If the response is not Y or y then the command is exited.

All holes on file for the current Bench and Blast are then read into the

working array.

GP

GET PERIMETER [/FG]

Gets a perimeter from the OUTLINES file. This allows an existing perimeter to be edited or used for limitation of blast-hole layout.

>>> ENTER REQUIRED PERIMETER NUMBER <<<

>VALUE > Enter required perimeter number.

The selected perimeter then becomes the current outline, replacing any existing perimeter.

LAY DOWN PATTERN [/BP]

Lay down pattern of holes. The currently selected hole pattern is laid down within the Blast outline and within any current perimeter, parallel to a given line, and with the first point specified by cursor. If there is no currently selected pattern (true on entry to LAYOUT) then the message is displayed:-

>>> No pattern selected - use SP <<<

and LAY DOWN PATTERN [/BP] exited.

Layout/Deletion of blast pattern

================================

The currently selected blast-hole pattern ( 1)

will be laid down within the Blast Outline

and within the current perimeter.

Use SP to Select a new Pattern;

DP to define/delete a perimeter.

Any existing holes within this region will be replaced.

Continue with deleting/laying down this blast pattern?

>[Y]/N > Enter <return> to continue or N or n <return> to exit LAY

DOWN PATTERN [/BP].

If there are any existing holes within the Blast (and any current perimeter) these will be deleted and the display refreshed.

Now select a line with cursor button F3

defining the orientation of the rows.

OR

Specify two points with cursor button F1

defining the orientation of the rows.

OR

Select a command to exit hole layout.

Either specify an existing line by moving the cursor into the vicinity of the line and pressing F3 (mouse button 3) or use F1 (mouse button 1) to specify two points defining a line. The rows of the blast-holes will be laid out parallel to this line.

Specify a point with cursor button F1 for the

first blasthole;

OR

Press cursor button F2 to respecify the line;

OR

Choose a new command to exit hole layout.

The point chosen will be the first hole in the first row of the pattern (unless an offset is specified in the next question).

Enter an offset distance from this point for the start

of the first row. (+ve downwards, -ve upwards)

>Distance > This offset distance will be for the first row from the point chosen. The distance is measured at right angles to the line of orientation.

The holes will then be laid out into the Blast (and within any perimeter specified). Each hole will be identified with a cross. Note that holes will have no number (BHID); this may be supplied later by the NUMBER HOLES [/BN] command. Any grade fields will be set to absent data.

LI

HOLE LIST [/BE]

List (display) all blast-holes in the working array.

Listing of holes

================

To screen [S] or printer (P) ?

>[S]/P > Enter <return> for a screen listing, or P or p to send a listing to the print device.

After every 20 records, the message is produced:-

>>> PRESS <RETURN> TO CONTINUE OR ! TO TERMINATE >

Enter ! to terminate the listing.

LS

LAYOUT PRE_SPLIT [/BL]

Lay out holes along a string. This is used for pre-split operations, or in cases where it is required to lay out holes at regular distances along a line.

Pre-Split Hole Definition

=========================

First define required string

End string by reselecting LS

A string may be defined in exactly the way done with the NEW PERIMETER [/EN] command, including use of the F3 button. Then this command is selected again.

Enter the offset of the first hole from the first point of the string.

>Offset of 1st hole?[0]> Enter the required start distance along the line for the first hole.

Enter the required interval of pre-split holes (>0)

>Hole interval > Enter the required distance between holes.

Do you want to displace string for another line of pre-split holes ?.

>[N]/Y > Enter Y to displace string a given distance and lay out more holes.

If the response way Y:-

Do you want to move the string to the right or left, looking in the direction that it was defined ?

>[R]/L > Enter R for right, L for Left.

>Displacement (>0) ? > Enter the required displacement.

The string will be moved the given distance, and then a new set of holes can be laid out.

NH

NUMBER HOLES [/BN]

Number holes. There are two modes of operation. The first is an automatic one; the holes within the entire blast are sorted on -Y and X (i.e. from the top to the bottom of the screen as shown) and then numbered in sequence. The second method is manual, in which holes are selected in the desired sequence by cursor.

Hole numbering

==============

Do you want Automatic numbering [A] or to specify the order Manually (M) or by distance from a defined string (S) ?

>[A]/M/S > Enter <return> for automatic numbering or M or m <return> for manual numbering, or S or s <return> for numbering by distance from a selected string.

For automatic numbering, there is no further input.

For manual numbering (M) :-

Enter first hole number required (1-9999) [1]

>Number> Enter required number >0, or <return> to use 1.

Select each hole in turn with cursor (F1)

Delete last selection with F2

End by selecting new command.

Select the holes in turn with the cursor (F1 or mouse button 1). The number will increment by 1 each time. To delete the LAST SELECTION ONLY, press F2. End by selecting a new command with the cursor.

For numbering by distance from a string (S) :-

Numbering by distance from a string

===================================

First define the string with cursor

End by reselecting the NH command.

A string may be defined in exactly the way done with the NEW PERIMETER [/EN] command, including use of the F3 button. Then this command is selected again.

Define a tolerance distance to be used in assigning holes to rows. Typically this is approximately the mean row spacing.

>Tol[5]> Enter a tolerance factor, default 5.

This is necessary because holes are sorted by their distance at right angles to the entered string, and then numbered by this sort distance. If exact distances were taken then holes in the same row would not be numbered in sequence. The distances are therefore rounded to Tol units before sorting.

Note that distances are computed from the ends of the string if there is no vertical intersection possible. Unless you want holes to be numbered radially about the ends of the string, extend the string so that there is a possible vertical intersection for each hole onto the string.

NS

NUMBER SAMPLES [/BM]

Number samples. Allows the first sample number and the number of samples for each hole to be set. Valid only if the fields NSAMP and SNFIRST exist in the &COLLARS file.

OH

ORIENT HOLES [/BO]

Orient the holes within the current perimeter. Allows the bearing, dip and length of the holes to be set. Valid only if the fields BRG, DIP and HLENGTH exist in the &COLLARS file.

PA

PL

MAKE PLOT FILE [/FM]

Make a plot file of the screen display.

>>> PLEASE SUPPLY PLOT FILE NAME

>DATAMINE FILENAME? > Enter plot file name.

PP

DISPLAY STRINGS [/DD]

Plot all perimeters on screen and any geology lines. This command acts as a toggle; the first time it is used, it turns on permanent plotting of perimeters and geology lines. The next use turns these off, and refreshes the screen. Once this command has been entered, the first 1200 points from the perimeter and the geology files that lie within the screen area are entered into the bank for use by an EDIT PERIMETER [/ED] or NEW PERIMETER [/EN] command.

RF

REFERENCE POINTS [/CC]

Define a new set of digitizer reference points (and recalculate the transformation coefficients). This command may be used at any time to redefine the location of the drawing on the digitizer; for example to move on to a new sheet. Details of the operation of this command are given with the description of the DIGITISER [/CD] command. Note that this command allows for new drawings or movements in the plane of the drawing. If you are positioning a drawing from another (or parallel) plane, you MUST indicate the change of view by selecting the RESET LIMITS [/DL] command first.

RU

MACRO [/CA]

Run a macro from a system file containing a set of commands for the LAYOUT process. Macros may not be nested, unless the final command in each is RU.

RUN A MACRO OF INTERACTIVE GRAPHICS COMMANDS

============================================

The macro must only contain valid commands

and their data. Nesting is not permitted.

Enter the name of the system file to execute

>SYSFILE> The system file name (up to 56 chars) containing the macro.

SD

BLASTHOLE DISPLAY [/CB]

If Y was entered, then you can make the annotation one of two colors; the default color below a given value of a field you will specify, or another color above or equal to this field value.

>>> Field for Differentiation [AAAAAAAA]

>Field >

Enter the required field name, or <return> to take the previous value. If the field does not exist, a list of available fields will be shown, and the question repeated.

>>> Enter value of this field above or equal to

>>> which the colour will change.

>>> This is an alphanumeric field [AAAA]

OR

>>> This is a numeric field [999999999.99]

>Value >

Enter the required value, or <return> to take the previous value.

>>> Required Colour ? [99]

>Colour>

Enter the required color, or <return> to take the previous color.

If automatic shading is in force, and the field is numeric and not all absent data, then the range will be divided over the first 12 shades. An attempt is made to choose reasonable starting points and intervals. If automatic shading is not in force, or all values are the same or absent data, then the user will be prompted for required colors and ranges:-

>>> ENTER FIELD NAME

>FIELD >

Field name to be shaded.

There are two modes of operation, depending on the default selected (see DEFAULTS [/CF]). On entry, or if manual shading has been selected in DEFAULTS [/CF], or the field is alpha, or numeric but all absent data, then:

A palette of shades is shown. One is selected by cursor, and the user is prompted:-

>FROM >

The lower bound for this shade.

>TO >

The upper bound.

BLASTHOLE DISPLAY [/CB] is terminated by selecting another command (e.g. REDRAW [/DR]) with the cursor. For macro or keyboard entry, the prompt CODE precedes the FROM. The required code number (1-5, 1126-1140) is entered. 0 terminates.

SM

SNAP MODEL [/CP]

Selects the mode of operation of function button F3 during the NEW PERIMETER [/EN] and EDIT PERIMETER [/ED] commands. On entry, function button 3 will select the nearest point from the point bank; this is known as point mode. If this command is selected, then the message:-

Button 3 will snap to lines

is shown, and line mode is entered.

In line mode, function button 3 will choose a point that lies nearest to the cursor, but on a line joining two connected bank points. Selecting this command again will change to Segment mode. The message shown is:-

Button 3 will snap to all segments between points

Select first, intermediate, then last points with F3

F3 is then used to choose the first point on an existing perimeter or string. This point defines the line that will be used.

Now select with F3 central point defining direction (F2 to abandon)

The second point is then selected with F3. This point defines the direction to take on the perimeter/string between the first and third points. Only points on the same line as the first point will be chosen.

Now select last point with F3 (F2 to abandon)

The third point is then selected with F3. This point is the final point on the perimeter/string to be included in the perimeter. All points between the first and the third, passing through the second, will then be added into the perimeter following the current point.

Selecting this command again will change back again to point mode, and the following message is shown:-

Button 3 will snap to points

This command may be chosen within the NEW PERIMETER [/EN] or EDIT PERIMETER [/ED] commands without exiting.

SP

SELECT PATTERN [/BS]

Select blast-hole pattern for use in LAY DOWN PATTERN [/BP] command. All patterns are first shown on the graphics screen. A maximum of twelve patterns may be defined. If there are no patterns on file, a message is displayed:-

>>> No patterns on file - use UP to define <<<

and SP is exited. Otherwise selection may take place.

Selection of blast-hole pattern

===============================

Enter required pattern number [ 1]

>Number> Enter required number >0, or <return> to use 1.

The selected pattern number remains in force until changed with a new SELECT PATTERN [/BS] command.

SU

>DATAMINE FILENAME? > Enter name of plot file.

This command plots the given name once. See the DEFAULTS [/CF] command for permanent plotting.

TI

TITLE [/DT]

Set title above plot. The prompt is:-

>>> PLEASE INPUT A TITLE UP TO NN CHARACTERS LONG

>TITLE > Enter title. Blank or ! to remove a previous title.

The number of characters NN in the title is a function of character size. This title will replace the pre-defined title giving the Bench and Blast numbers. Use REDRAW [/DR] to re-draw after using this command.

UP

UPDATE PATTERN [/BU]

Update blast-hole pattern on file. This command may be used to add new patterns or change existing ones. First all existing patterns are shown on the graphics screen.

Addition/Modification of Blast Patterns

=======================================

Enter the pattern number (1-12) you wish to define.

If this pattern exists, it will be overwritten.

If it does not exist, it will be added.

Enter <return> to terminate UP.

>Number>

Enter a pattern number (1-12) or <return> to terminate UP.

Entry of new blast pattern number nn

====================================

Patterns are entered row by row as shown below:

-------------------------------

|

|--XS1--x-d1-x x x Row 1

| d2

|---XS2----x x x x Row 2

Where XS values are the distance from the left of the pattern start to the first hole; d1 is the X spacing between holes and d2 is the Y spacing between rows. Up to 5 different rows are permitted. The pattern repeats after all rows have been entered.

First enter the X spacing (between holes) and the Y spacing (between rows).

>X Spacing >

Enter a spacing (>0).

>Y Spacing >

Enter a row spacing (>0).

Enter row number and X offset of first hole:-

End by giving a Row of zero

>Row >

Enter row number, starting with 1 (max 5). You may re-enter a previously entered row by specifying its number again. Do not leave out row numbers (e.g. do not give rows 1 and 3 without 2). End with 0.

>X Dist>

Enter the offset for this row. Row 1 should normally have an offset of 0.

These last two prompts are repeated until a row of 0 is entered.

Enter an up to 16 character description

>Descript'n>

This description will be entered into the PATTERNS file and displayed whenever the new pattern is shown by SELECT PATTERN [/BS] or UPDATE PATTERN [/BU].

The new (or modified) pattern will then be written to the PATTERNS file. All patterns are then shown on the screen and the first prompt repeated. Enter <return> to exit UPDATE PATTERN [/BU].
