EXTERNAL Printing—Dynamic Program Call

With the Dynamic Program Call interface, CA View dynamically loads and calls a program to handle the print request. The following information is passed to the program:

• The external print record (XPR)
• The parameter data specified in the EXTPRTn initialization parameter
• The destination specified by the user on the print request.

To select a SYSOUT group for printing by the external printing product, specify a destination (DEST field of a Print Attribute panel) using the following format:

>printer-id.parameter-data

where:

>

Signifies that the SYSOUT group is to be printed by an external printing product

printer–id

The 1- to 3-character external print identifier that matches the value you set for the corresponding EXTPRTn initialization parameter

parameter–data

The additional parameter data to be passed to the interface program

Example

Assume the following:

• You want to print to an external device using the Dynamic Program Call Interface
• The printer ID is ANA
• The program to be called is ANAEP
• The characters NOBANNER are to be passed to the program.

Your system administrator might define the following initialization parameter:

EXTPRT2=ANA/PGM/ANAEP/NOBANNER

For the online print request by the user, specify the following destination:

DEST ===> >ANA.INDEX

CA View dynamically loads and calls the program ANAEP. The parameter list to the program contains the addresses and lengths of the following:

• The character string NOBANNER
• The character string INDEX
• The XPR record
