ACCMLT Process

To access this process:

• Display the Find Command screen, select ACCMLT and click Run.
• Enter "ACCMLT" into the Command Line and press <ENTER>.

See this process in the Command Table.

Process Overview

ACCMLT accumulates values for constant values of keyfields.

For example, if a file contained the fields YEAR, MINE, CuProdn, AuProdn then subtotals of CuProdn and AuProdn for each value of YEAR over all values of MINE could be produced.

The output is a new file containing the keyfields and the totals. The format is identical to the input file, except that all alphanumeric fields are eliminated, unless they form part of the keyfields.

Important: the input file should be sorted on the keyfields beforehand. If it is not, then totals will be for each set of sequential keyfields with the same value in the file.

Input Files

Name	Description	I/O Status	Required	Type
IN	Input file.	Input	Yes	Table

Output Files

Name	Description	I/O Status	Required	Type
OUT	Output sub-total file.	Output	Yes	Table

Fields

Name	Description	Source	Required	Type	Default
KEY1	Keyfield 1 for totalling.	IN	No	Any	Undefined
KEY2	Keyfield 2.	IN	No	Any	Undefined
KEY3	Keyfield 3.	IN	No	Any	Undefined
KEY4	Keyfield 4.	IN	No	Any	Undefined
KEY5	Keyfield 5.	IN	No	Any	Undefined
KEY6	Keyfield 6.	IN	No	Any	Undefined
KEY7	Keyfield 7.	IN	No	Any	Undefined
KEY8	Keyfield 8.	IN	No	Any	Undefined
KEY9	Keyfield 9.	IN	No	Any	Undefined
KEY10	Keyfield 10.	IN	No	Any	Undefined

Parameters

Name	Description	Required	Default	Range	Values
ALLRECS	Accumulation flag (0). If set to 1 then all records will be copied to the output file showing the cumulative totals.	No	0	0,1	0,1
UNSORTED	Unsorted flag. Default (0). Option Description 0 - An accumulated total is written to the OUT file every time the keyfield[s] changes. Hence, if the IN file is sorted on the keyfield[s] there will be 1 entry in OUT for each keyfield[s] value. If IN is not sorted on the keyfield[s], there may be multiple entries for the same keyfield[s] value in the OUT file. 1 - The accumulation is over all records with the same keyfield[s] value. Hence there will only be 1 entry in OUT for each keyfield[s] value, irrespective of whether the IN file is sorted or not. N.B. If UNSORTED=1, the cumulative totals option ALLRECS cannot be used. The process will automatically set ALLRECS to 0 if UNSORTED=1.	No	0	0,1	0,1

Notes

The total keyfield value must be no more than 5 words long.

Remember that an alphanumeric field must be 24 characters or less.Example

!ACCMLT &IN(PRODN),&OUT(TOTPRODN),*KEY1(YEAR)
>>> 3000 RECORDS READ
>>> 3 DIFFERENT KEY OCCURRENCES FOUND

Error and Warning Messages

Message	Description
>>> NO NUMERIC FIELDS TO ACCUMULATE	ACCMLT accumulates all numeric fields which are not part of the key, but there were none. Fatal; the process is exited.
>>> WARNING - VALUE OF FIELD nnnnnnnn TOO LARGE >>> ON RECORD NUMBER mmmmmmmm - IGNORED	A value greater than or equal to TOP was found. Warning; the record is ignored.
>>> ERR 47 <<< ( 0) IN FNDKEY	Warning; none of the specified key fields exist in the input files. Accumulation is carried out over all records.
>>> KEYFIELD aaaaaaaa MISSING FROM FILE ffffffff	A warning message that is produced if @PRINT >=1. The keyfield is ignored and processing continues.
