Translating command-level statements in a CICS program

Prepare your CICS program in either of these sequences:

• Use the DB2® precompiler first, followed by the CICS Command Language Translator. This sequence is the preferred method of program preparation and the one that the DB2I Program Preparation panels support. If you use the DB2I panels for program preparation, you can specify translator options automatically, rather than needing to provide a separate option string.
• Use the CICS command language translator first, followed by the DB2 precompiler. This sequence results in a warning message from the CICS translator for each EXEC SQL statement that it encounters. The warning messages have no effect on the result. If you are using double-byte character sets (DBCS), precompiling is recommended before translating, as described previously.

If your source program is in COBOL, you must specify a string delimiter that is the same for the DB2 precompiler, COBOL compiler, and CICS translator. The defaults for the DB2 precompiler and COBOL compiler are not compatible with the default for the CICS translator.

EXEC CICS ADDRESS
     TWA (address-of-twa-area)
END-EXEC

You can run CICS applications only from CICS address spaces. This restriction applies to the RUN option on the second program DSN command processor. All of those possibilities occur in TSO.

To prepare an application program, you can append JCL from a job that is created by the DB2 Program Preparation panels to the JCL for the CICS command language translator. To run the prepared program under CICS, you might need to define programs and transactions to CICS. Your system programmer must make the appropriate CICS resource or table entries.
