Handling an Incompletely Processed DELETE

If IXLLIST cannot find a list entry list you have specified in your entry list, processing ends prematurely and the entry list index of the entry that couldn't be found is returned in the LAAFAILINDEX field of the answer area. To continue processing, reissue the request starting with the entry after the one that couldn't be found (LAAFAILINDEX+1).

A DELETE_ENTRYLIST request can also time out before finishing all its processing. If this happens, IXLLIST:

Sets the IXLLIST return code to IXLRETCODEWARNING and the reason code to IXLRSNCODETIMEOUT to indicate that processing did not complete.
Returns in the LAADELCNT field of the answer area, the count of list entries that have been deleted on that invocation.
Returns in the LAAFAILINDEX field of the answer area, the index of the first unprocessed entry in the list of entry names or entry IDs you have specified for deletion.

All entries preceding the failing list entry will have been deleted and all entries beginning with the failed entry will still remain to be processed. To continue processing, reissue the DELETE_ENTRYLIST request using the index value returned in LAAFAILINDEX as the value of the FIRSTELEM parameter. Continue reissuing the request until the return code indicates that all the processing has completed.
