This user exit is named EZAPPGPR. It changes JES or VTAM® input parameters and is invoked before the routing or options data is read (routing data areas are created.) It can replace the functions of the routing or options files because you can use it to create the RDA itself or change the key used to access the files. To invoke EZAPPGPR, it must be in a library specified by a JOBLIB, STEPLIB, or in the LNKLIST.

This user exit is user-named and is invoked in one of two ways:

1. After the general routing exit completes
2. After the Network Print Facility creates the routing data area

It can modify the RDA or change or augment the data obtained from those sources. To invoke the specific routing exit, it must be a LINKLST member of MVS™ PARMLIB or specified on either the JOBLIB or STEPLIB DD statements.

Input record exit

This user exit performs two functions:

1. Allows modification of the RDA.
2. Allows the alteration of the contents of data to be printed. This can be used to insert, modify, or delete application data as needed to accommodate output to destined printers.

This exit is invoked for all data-related functions in NPF processing.

See Using the EZAPPFCD macro to produce the DSECTS needed for the exits.
