Using the interval control request token UEPICTOK

UEPICTOK provides the address of a 4-byte area that you can use to pass information between the XICEREQ and XICEREQC user exits for the same interval control request.

For example, the address of a piece of storage that is obtained by the XICEREQ user exit, which is to be freed by the XICEREQC exit, can be passed in the UEPICTOK field.

UEPICTOK is usable only for the duration of a single interval control request, because its contents might be destroyed at the end of the request. If you need to pass information between successive invocations of a global user exit, you can use task token UEPTSTOK to do so. For more information about UEPTSTOK, see Using the task token UEPTSTOK.
