Resuming IRL Programs
NF BC Working With IRL
7
You can exit an IRL program, perform other functions (such as execute DOS
commands, run other IRL programs, or put the reader in Suspend mode), and
then resume the IRL program exactly where you left off.
Exiting a Program So You Can Resume It Later
You can resume an IRL program if you exit it using one of these methods:
• Execute the IRL Program, Exit (/$) command. You can scan a bar code that
contains the command, or send the command from a host computer.
• Add to your IRL program an Exit command with a D modifier (ED). When
the ED command executes, the program terminates and returns you to the
DOS prompt.
• Press the application break sequence, as described in “Breaking Out of an
Application” in Chapter 9.
You can exit multiple programs that can all be resumed later. IRL creates a
filename.RSM file in the data file path for each program, where filename is the
program name. The .RSM file contains information that lets IRL resume the
program exactly where you left off. IRL deletes the .RSM file when you run or
resume the program.
IRL also saves the name of the last program that was exited as described
previously into the {LATEST}.RSM file. Every time IRL saves the filename to
this file, it overwrites the last filename; therefore, the file always identifies the
last IRL program that can be resumed. IRL deletes this file when you run or
resume the program.
