Specifying the template/copybook for a data set

To describe the structure of a data set you can use:

• A COBOL copybook
• A HLASM copybook
• A PL/I copybook
• A File Manager template

The JCL generated by FM/Db2 for the various batch functions always uses the TCIN or TCOUT batch keywords, as described below:

TCIN

For functions where there is an input data set (import)

TCOUT

For functions where there is an output data set (export)

When it is necessary to specify the template/copybook data set name in the JCL statements, rather than via a File Manager batch keyword, you can use the alternative keywords TINPUT and TINMEM, or TOUTPUT and TOUTMEM.
