Defining the library-processing output file (SYSMDECK)

The SYSMDECK DD allocation is required for all compilations. If you specify the MDECK compiler option, the SYSMDECK DD allocation must specify a permanent MVS™ data set or a z/OS® UNIX file. However, if you use the NOMDECK option, SYSMDECK can alternatively be specified as a utility (temporary) data set.

The following example specifies a permanent dataset name:

//SYSMDECK DD DSNAME=dsname,UNIT=SYSDA

The following example specifies a z/OS UNIX file:

//SYSMDECK DD PATH='/path/filename.dek',
//FILEDATA=TEXT,                                
//PATHOPTS=(ORDWR,OCREAT,OTRUNC),              
//PATHMODE=(SIRUSR,SIWUSR)

The following example specifies a utility (temporary) data set:

//SYSMDECK DD UNIT=SYSALLDA

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.
