Using cataloged procedures for z/OS® XL C

You can use one of the following IBM-supplied cataloged procedures. Each procedure includes a compilation step to compile your program.

EDCC: Compile a 31-bit or 64-bit program
EDCCB: Compile and bind a 31-bit program
EDCXCB: Compile and bind a 31-bit XPLINK C program
EDCQCB: Compile and bind a 64-bit C program
EDCCL: Compile and link-edit a 31-bit naturally re-entrant program
EDCCBG: Compile, bind, and run a 31-bit program
EDCXCBG: Compile, bind, and run a 31-bit XPLINK C program
EDCQCBG: Compile, bind, and run a 64-bit C program
EDCCLG: Compile, link-edit, and run a 31-bit program
EDCCPLG: Compile, prelink, link-edit, and run a 31-bit program
EDCCLIB: Compile and maintain an object library for a 31-bit or 64-bit application

IPA considerations

The EDCC procedure should be used for the IPA compile step. Only the EDCI and EDCXI procedures apply to the IPA link step. For information on the EDCI and EDCXI procedures, see Using the IPA link step with z/OS XL C/C++ programs.

To run the IPA compile step, use the EDCC procedure, and ensure that you specify the IPA(NOLINK) or IPA compiler option. Note that you must also specify the LONGNAME compiler option or the #pragma longname directive.

To create an IPA-optimized object module, you must run the IPA compile step for each source file in your program, and the IPA link step once for the entire program. Once you have successfully created an IPA-optimized object module, you must bind it to create the final executable.
