PIE2TAB PIB2TAB describes the entries in the PIE2TAE bleck, which is an extension of the PIETAE tlock. For each PIB table entry, an entry exists in the PIB table extension block
(PIB2TAB) • The PIB2PTR field in the BGCOM block points to the PIE2iAB tloek.

PUEltB PUBIDR defines the fields of a physical unit block table as used by CMS and/or DOS routines. Both DSECTs define the same storage. I • For Use by CMS Routines (MIPPUB macro)
The simulated PUBADR DSECT has eighteen 8-byte entries, one for each device sUPForted by CMS. The simulated PUBADR DSECT is invoked by the MIPPUB macro.
