Code page conversion

CICS provides facilities to convert HTTP messages into a code page that is suitable for a user application program, or suitable for use on the Internet. CICS handles code page conversion using z/OS conversion services.

The code page conversion table (DFHCNV), which was required in earlier CICS releases, is not normally required for CICS Web support in CICS Transaction Server for z/OS, Version 3 Release 1. The exception is if you want to use an analyzer program that you coded in an earlier CICS release to reference DFHCNV. In this case, you must either continue to supply the code page conversion table, or make an update to the analyzer program. Migrating entries in the code page conversion table (DFHCNV) has more information about this.
