I don’t know about anyone else, but I could not fathom the custom loadlib approach presented in the R18 standard install process. As soon I just came to see the #SVCOPT would be assembled outside of SMP/E I knew this approach was never going to work for me. What is presented here are usermods to replace part of the install JOB3 that is now generated by CAISAG. Ver. 1.1: Added UMOD for #CTABGEN and corrected some typos in previous comments, may still be useful for 18.0 users.
UMODr185.zip Version 2 (1.4 on the old site) has usermods changed for 18.5 and also includes three CICS usersmods.
Version 3, October 1, 2014 - Added new UMODUCB for UCF Batch to allow RETCD=NO.
