Exit 12: ISPF service start exit

The ISPF exit for the service start lets you monitor all external ISPF service requests. Exit routines at this user exit are notified of all service requests (including PDF services) made through the ISPLINK or ISPEXEC interfaces. The exit routines are not notified for ISPF internal service requests (those that do not use the ISPLINK or ISPEXEC interfaces.)

After initial verification of parameters and syntax, ISPF calls the exit routines at this user exit before the requested service is performed.

Exit parameters

In addition to the standard exit parameters described in Exit parameter list, the exit routines at this user exit receive these parameters. ISPF ignores any changes the routines make to these parameters.

servname

An 8-character field containing the name of the ISPF service being invoked. The name is left-justified within the field.

Flags

4 bytes of bit flags defined as follows:

0: 1 = ISPF service 0 = PDF service
1-31: Reserved.

Return codes

No return codes are acknowledged at this user exit. When this exit returns to ISPF, normal processing continues.

Note: For multiple exit routines, return codes still affect the processing flow.
