MENU Macro Process

To access this process:

Enter "MENU" into the Command Line and press <ENTER>.

Macro Process Overview

Initiates the currently established menu. The menu name is requested. This must be the name of a binary random access menu file which was created using the !LOADCF command.

!MENU commands should not be nested. A menu may be called from a macro or another menu, and a menu may call a macro.

On executing the !MENU command for the first time for any menu, there will be a delay while the menu is scanned and labels etc. entered into the system stack file. This stack file (of form<name>.STK, where <name> is the menu file name minus the extension) is saved, and on second and subsequent uses of the !MENU command, the stack file is copied for direct execution. This means second and subsequent uses of !MENU start execution much faster than the first time.

> If the stack file should not match the menu file, then the menu may not work correctly. This could happen if the binary menu file was overwritten (not by the !LOADCF command), leaving an old stack file in place. If this should happen, reload the menu using !LOADCF.

The total number of labels used within the menu file should not exceed 250. If this number is exceeded, all labels beyond that will not be accessible.

Example

!MENU

NAME >MYMENU
