# User Exit Defaults

User exits are sets of CALLNATs in PAC. Each such set is a set of CALLNATs of a subprogram of a particular name documented in PAC Reference documentation. The user can write the subprogram himself using the parameters described in PAC Reference documentation. If then the subprogram is catalogued in SYSPAC or its step library and the user exit is "switched on" by the PAC administrator with the facility described in this section, the subprogram will be called in certain situations. If the subprogram is available, but the user exit is not switched on, the CALLNATs of the exit are bypassed. If the user exit is switched on, but the subprogram is not available, NAT0082 occurs. Apart from the subprogram names PAC user exits have numbers. There are 37 of them, numbered as follows: 1-28, 30-32, 34-38, 40.

For each (numbered) PAC user exit, there is a switch at any time set to NO (N) for "off" or YES (Y) for "on". To see or modify these settings enter Code U on the General Defaults menu.

The User Exit Defaults menu appears:

In the first case, a Display User Exits screen appears; in the second case, the following Modify User Exits screen appears. The two screens differ in that, on the first screen, the fields of the first column containing the settings of the switches are protected while, on the second screen, they are not.
