Each SLU's routing file record optionally contains the name of the EZAPPPFT table entry to be used for sessions involving that SLU. These table entry name references in the routing file can be explicitly coded through the DEF PAGE FORMAT field in an ISPF panel (see Figure 2) or through an assembly using the DFPNAME field of the EZAPPFL macro. If you do not code a table entry reference, the Network Print Facility sets up the routing file record with its table entry name set to blanks.
