Abstract
RPGLE-RUN-PERFM UNNECESSARY CALLS TO QUSRJOBI DURING *INIT PHASE
FOR A MODULE
Error Description
An ILE RPG module or program compiled with TGTRLS(V7R2M0) may
make unnecessary calls to QUSRJOBI during module initialization.
Module initialization occurs when the first procedure in the
module is called, and for a cycle-main module, when the main
procedure is called again if previous call to the main procedure
ended with *INLR off, or it ended abnormally.
Problem Summary

* RECOMMENDATION: *
****************************************************************
An ILE RPG module or program compiled with TGTRLS(V7R2M0) may
make unnecessary calls to QUSRJOBI during module initialization.
Module initialization occurs when the first procedure in the
module is called, and for a cycle-main module, when the main
procedure is called again if previous call to the main procedure
ended with *INLR off, or it ended abnormally.
Problem Conclusion
The ILE RPG compiler will be change so that QUSRJOBI is only
called during module initialization when it is necessary.

Comments
Circumvention
- Compile with TGTRLS(V7R1M0)
- If the module has a cycle-main procedure, reduce the number
of times that module initialization is done by returning with
LR off.
