Wow, this one was perplexing.
I had a requirement to create a nightly backup that was effectively static, and included LIB(*ALLUSR). However, as more development libraries are created, they wanted the ability to omit these unnecessary development libraries from the backup.
I've been looking at QSRSAVO for a day or so because on the SAVLIB and SAVOBJ commands there is a new parameter CMDUSRSPC (Command User Space) that may include the omit list. However formatting it is a be daunting.
But after a few hours, I managed to get it working and all is well. The side effect is that I also lost my Virtual Tape cherry which was good.
I'll be including this feature in COZTOOLS free RT library in the next point release. But right now it only sets the omit list (no way to change it, just replace it). Once I create ADDSAVLE/RMVSAVLE (Add/Remove Save List Entry) in addition to the CRTSAVL that I've already built, I'll feel better about publishing it.
Let me know if this is something people are interested in utilizing.
