PAGEDEFs and FORMDEFs can be specified in the JCL of the job that produces the output using the PAGEDEF and FORMDEF parameters. The PAGEDEF and FORMDEF parameters can appear only in an OUTPUT statement.
A PAGEDEF can also be specified using the FCB parameter in a DD statement. When using this method, the following restriction must be taken into account: The FCB parameter is limited to four characters, and a PAGEDEF name can be up to six characters.
If a PAGEDEF and/or FORMDEF is not specified in any of the above, the default PAGEDEF and/or FORMDEF specified in the PSF procedure is used.
