User Exits

The CA Spool system allows the installation site to enforce its printer-handling and security standards by using exit routines.

Sample user exit routines are distributed with CA Spool. These routines can be used without any modifications, or an installation can modify the routines to suit individual requirements.

The following user exit routines are supplied:

• Security Exit, which is called whenever a file is accessed, or a network command is issued
• Interface Exit, which is called when a CA Spool request is issued through the Call Interface, the SUBSYS Interface, or the JESTOESF File Transfer Interface
• ESFTOJES Exit, which is called when a file is being transferred from CA Spool to JES
• Separator Page Exit, which is called before and after printing a spool file to a printer
• Output Limit Exit, which is called whenever a spool file being created exceeds its output limit
• Output Priority Exit, which is called to calculate the priority of a spool file when it is permanently closed
• Printer Exit, which can be called:
  • before a new line is to be printed
  • at start of the file or at end of the file
  • at the top of each page
  • before the printer session is established and after the printer session is established

    This exit can be used to send special control characters to laser printers, to select fonts, to shift orientation, and so on.

• Various CA Spool Main Task User Exits, which are called when specific internal events occur in the CA Spool main task
