The version of CDBADBRM must be available and found within the
DSNAMExx member on the //GENFREE0 EXEC //PTIPARM DD.
The PLANS and DSNAME members that are read are controlled via the following
in the //GENFREE0 | //SYSTSIN DD:
So create PLANS15 and DSNAME15 members and
update the PLANS15 member with the r15 plan names and the DSNAME15
member with the r15 CDBADRM.
This would be for Freeing from Rel 15. Use the same approach for other releases for which Plans/Packages need to be FREED.
