MFS page delete function

The MFS page delete function is not available for use by an ISC session.

OPTIONS=NPGDEL is forced on the IMS system definition TERMINAL macro statement or an ETO user descriptor, because paging requests other than QMODEL-architected paging requests are not supported. This includes MFS operator control table requests and other forms of input data that might occur during output demand-paging. An error (exception response and appropriate ERP message) occurs if data other than a valid QMODEL paging request is received during demand-paged output. The output message is returned to the queue as a result of the error condition and retransmitted at the next opportunity. If the output demand-paged message is conversational or response mode output, it is immediately resent and input is not allowed until the output message is successfully transmitted or dequeued by a valid QMODEL paging request or appropriate ERP action.
