What does a Roscoe CMD02 COMMAND LIMIT EXCEEDED message mean?
This is a message from a running RPF designed to avoid loops. Roscoe will issue the CMD02 message after a RPF program executes a site specified number of instructions without an intervening I/O instruction.
The Roscoe SYSIN parameters LOOP, LOOPDFLT and LOOPRST allow the site system programmer to control the loop limits.
- The LOOP parameter defines the maximum number of RPF statement can be executed without an intervening read or write operation.
- The default limit, set by LOOPDFLT=, is the value that permits the average program to execute without being paused.
- LOOPRST=YES permits users to override the statement count limits via the “SET STMTCNT” command. This command should be used selectively as it removes all loop protection.
