SAP – Standalone Error Handling
This command determines at what line a program will restart after an error is cleared. When an error occurs in a standalone program, it will automatically jump to subroutine 31. Typically, the user will establish an error-handling routine to cancel the error. The SAP command indicates where the program should return – either jump back to the first line in the program or return to the line following where the error occurred.
Applies to: CMD-4CR, CMD-4EX-SA, PMX-4EX-SA, PMX-4ET-SA, PMX-2ED-SA, PMX-2EX-SA
