The default code page used by z/OS® Debugger and the remote debuggers is 037. For any of the following situations, you need to use a different code page:
- Application programmers are debugging in remote debug mode and
the source or compiler use a code page other than 037.
If your C/C++ source contains square brackets or other special characters, you might need to specify an EQAOPTS CODEPAGE command to override the z/OS Debugger default code page (037). Check the code page specified when you compiled your source. The C/C++ compiler uses a default code page of 1047 if you do not explicitly specify one. If the code page used is 1047 or a code page other than 037, you need to specify an EQAOPTS CODEPAGE command specifying that code page.
- Application programmers are debugging in full screen mode and
encounter one of the following situations:
- They use the STORAGE command to update COBOL NATIONAL variables.
- The source is coded in a code page other than 037.
- Application programmers use the XML(CODEPAGE(ccsid)) parameter on a LIST CONTAINER or LIST STORAGE command to specify an alternate code page.
z/OS Debugger uses the z/OS Unicode Services to process characters that need code page conversion.
The following diagram describes the syntax of the CODEPAGE command:
>>-EQAXOPT--CODEPAGE--,--nnnn----------------------------------><
- nnnn
- A positive integer indicating the code page to use.
After implementing the EQAOPTS CODEPAGE command, if application programmers using full-screen mode still cannot display some characters correctly, have them verify that their emulator's code page matches the code page of the characters they need to display.
You might need to create your own conversion images as described in Creating a conversion image for z/OS Debugger.
