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.

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 shared library (.so) file, using the charset(ASCII) and dialect(MF) directives.
Make a backup copy of the existing MFCCSIDMAP.so file located by default in $COBDIR/bin.
Copy your new MFCCSIDMAP compiled program file to the $COBDIR/bin directory, overwriting the existing file.
