ISFSYSTB Prolog
NAME : CSEBLOKS
DESCRIPTION: Definition tables for Cross System
Extensions
DSECT : ISFSYSTB (primary)
RELOCATION CONSIDERATIONS : None
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.

CSL layout of systemname table. DSECT is mapped on:
ISFNTABI - table in HCPXSY
0000 0 Character 8 ISFNAME system name
00000008 ISFNLEN *-ISFNAMTB length of one entry
00000038 ISFINMAX 56 A (somewhat) arbitrary limit
of the number of system names
that we will allow for the
XLINK_SYSTEM_INCLUDE list of

imposed on the system names
specified in the CSESYS macro in
HCPSYS by the local assembler
arithmetic variable &MAXSYS,
which is defined in macro
CSESYSLN.
