Return codes
All the possible return codes are contained in a CICS®-supplied copybook, which you must include in the program source of your external, non-CICS program.
The names of the copybooks for the supported languages,
and the libraries that they are supplied in, are shown in
Table 1.
| Copybook name | Language | Library |
|---|---|---|
| DFHXCRCD | Assembler | CICSTS56 .CICS.SDFHMAC |
| DFHXCRCH | C | CICSTS56 .CICS.SDFHC370 |
| DFHXCRCO | COBOL | CICSTS56 .CICS.SDFHCOB |
| DFHXCRCL | PL/I | CICSTS56 .CICS.SDFHPL1 |
z/OS® provides copybooks for use with the interfaces described in Use of sync points in the client program. These are described in z/OS MVS Programming: Resource Recovery and z/OS MVS Programming: Callable Services for High-Level Languages.
