CSIRESNM is the name of the catalog entry on which the search will resume if the work area space for return information is used up. If the request can be resumed, CSIRESUM will be set to Y on return from the call to CSI, CSIRESNM will contain the name of the entry on which to resume, and CSICATNM will contain the name of the catalog in which the entry to be resumed was found. Normally, the application program will test CSIRESUM, and if it is Y, the application program will reissue the call to CSI without changing CSIRESNM and CSICATNM.
