To specify the corresponding ASCII CCSID for an EBCDIC CCSID

Note: To complete this task, you must have administrator privileges to the Enterprise Developer installation directory.

Install both the EBCDIC and ASCII CCSIDs. See To install CCSID tables for details.
Specify the EBCDIC CCSID in the SIT. See To specify a CCSID table in the CICS SIT for details.

Code a COBOL module named MFCCSIDMAP, inserting the following code:

       linkage section.
       01 lk-ccsid                     pic x(4) comp-5.

       procedure division using by reference lk-ccsid.
           if lk-ccsid = EBCDIC-CCSID
               move ASCII-CCSID to lk-ccsid
           end-if
           goback.

Where EBCDIC-CCSID is the CSSID specified in the SIT and ASCII-CCSID is the corresponding ASCII CCSID.

Compile MFCCSIDMAP to a dynamic link library (.dll) (Windows) or shared library (.so) (UNIX) file, using the charset(ASCII) and dialect(MF) directives.
Make a backup copy of the existing MFCCSIDMAP.dll (Windows) or MFCCSIDMAP.so (UNIX) files located by default in %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\bin and \bin64 (Windows) or $COBDIR/bin (UNIX).
Copy your new MFCCSIDMAP compiled program files to the %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\bin and \bin64 directories respectively (Windows) or $COBDIR/bin (UNIX) directory, overwriting the existing files.
