The autoinstall user program at DELETE

To provide symmetry of control over the autoinstall process, the autoinstall user program is invoked when an autoinstalled IPCONN resource is deleted.

Invoking the user program at DELETE enables you to reverse the processes carried out at the INSTALL event. For example, if the user program at INSTALL incremented a count of the total number of automatically installed resources, then the user program at DELETE would decrement that count.

Input to the program is by a communication area, addressed by DFHEICAP. The layout of the communication area is shown in Figure 1.
