ISFSYSTB
Cross Reference (Contains links to field and bit definitions)
ISFSYSTB Prolog
NAME : CSEBLOKS
DESCRIPTION: Definition tables for Cross System
Extensions
DSECT : ISFSYSTB (primary)
STATUS : VM/ESA Version 2, Release 4.0
Notes : - Tables are built during system initialization and
system configuration file processing.
- Only ISFSYSTB is included in the PL/X version of
this control block. Fields in ISFSYSTB are initialized
using the Assembler version of the table, therefore
initial values are not included in the PL/X version.
HISTORY : The PLX portion of this block was created
for PITS 2T0H788.
