Defining the library-processing output file (SYSMDECK)

The SYSMDECK data set is required for all compilations. If you specify the MDECK compiler option, the SYSMDECK DD allocation must specify a permanent data set. However, if you use the NOMDECK option, SYSMDECK can be specified as a utility (temporary) data set.


//SYSMDECK DD DSNAME=dsname,UNIT=SYSDA

The SYSMDECK file will contain a copy of the updated input source after library processing, that is, the result of COPY, BASIS, REPLACE, EXEC SQL INCLUDE, and EXEC SQLIMS INCLUDE statements. The file can be a traditional MVS™ data set or a z/OS® UNIX file.
