data

When you generate a COBOL program for z/OS®, the data build descriptor option specifies whether to use the DATA(24) or DATA(31) compile option to prepare a generated COBOL program.

Values

31 (the default value): Specifies that the DATA(31) compile option is to be used.
24: Specifies that the DATA(24) compile option is to be used. You must specify 24 for any program that is linked AMODE(24) or that is in the same run unit as another program that is linked AMODE(24).
For CICS® for z/OS, you can specify 24–bit addressing only if the dynamic storage required by the generated COBOL program, library, service, form services program, or DataTable program is less than 64KB.
