After a run of SARPAC, the client saw that their old tapes still remaining in the SARPAC tape list indicating that one active report still remained on the tape.
In this instance, the client was performing SARPACs using "//SYSIN DD ..." of TAPESEQ=nnnnn (single tape), and the tapes in question had, at their beginning, a continuation of a report.
As SARPAC cannot move a partial report, the tapes (despite having other reports being moved) continued to hold the partial report.
The client was advised to do the following, for future SARPACs of this type:
. Run a SARTCP TAPEMAP, to determine if the targeted tape contains any partial reports, either at the beginning of the tape or at the end of a tape (where the report would finish on a subsequent tape).
. If not, then that solo tape can be input to SARPAC.
. If so, then determine what other tapes surrounding that tape contain the other pieces of the partial reports, continuing that process until there is a tape range to input to SARPAC, whereas there are all complete reports.
