Issue/Introduction

On one Gen client/server Windows/z/OS environment the GUI client displays characters "[]" correctly.
However, on another environment it does not i.e.
[ is getting displayed as ¢
] is getting displayed as !

Environment

Release: 8.6

Component: CA Gen Run Time, Distributed

 

Resolution

On z/OS International code page/CCSID 500 is being used rather than the usual US code page/CCSID 037.

Updated the Gen z/OS National Language user exit TIRXINFO from default US EBCDIC codepage 37 to International EBCDIC codepage 500 which has fixed the issue:
 DEFCODEP DC    CL8'00000500'            DEFAULT CODE PAGE

TIRXINFO - National Language Information Exit

This differences page explains why the problem was being seen on the Gen GUI client
Conversion character differences between CCSID 037 and CCSID 500
i.e. 
0x4A is ¢ under codepage 37 and is [ under codepage 500
0x5A is ! under codepage 37 and is ] under codepage 500
So when using default codepage 37 that matches what was shown i.e. ¢ instead of [ and ! instead of ]

After the change  DLLs TIRCRUNC and TIRXINFZ are rebuilt using MKCRUN and did a NEWCOPY of those 2 DLLs in CICS:
