Express alternate PCBs

The IMS Spool API supports the use of express alternate PCBs. If the application program issues a purge (PURG) call against an alternate PCB that has been generated with EXPRESS=YES, the print data set is closed and deallocated. It is available for JES processing before the termination of the IMS unit of work.
