BMCLIBA/B
BMCLIBA and BMCLIBB contain BMCLOADLIB members. When one of these libraries is active (in use by the online product), the contents of BMCLOADLIB are copied to the other, or inactive, library for use in the next online change run.
Prior to running online, you should APF authorize these data sets to the MVS system.
BMCLOADLIB, BMCLIBA, and BMCLIBB should have the same BLKSIZE.
