SYSVAR
The problem:
From 2.4 on it is possible to set variables (SETPARM) lasting for POWER-JOB
duration and for SYSTEM duration. While with power-job duration variables
this might not be a problem, but for system wide variables, there is no
way to list what is defined nor a way to delete a specific variable.
The solution:
With SYSVAR you get a program (with source), that can list or delete a
system-variable.
JCL how to use it is included.
The program is written with relative and immediate instructions and
does not have a base-register for the code (but for the data-areas). If
your CPU does not have these instructions, you can easy change the source
to use the old ones.
