TSOBLKS Prolog
Name : TSOBLKS
Description: TSO Control Blocks
DSECT : TSOBLKS
Function : The TSOBLKS macro contains two DSECTS: TSOBLKS
and CMSTAXE. Information on both DSECTs is
included in this section. TSOBLKS - TSO Control
Blocks The TSOBLKS DSECT describes the entries
in the TSOBLKS block which contains OS control
information used by CMS, that is, the command
program parameters list (CPPL), user profile
table (UPT), protected step control block
(PSCB), and the environment control table
(ECT). The ATSOCPPL field in NUCON points to
TSOBLKS block.
