Troubleshooting with WER999A UNSUCCESSFUL SORT
WER999A indicates that an error condition occurred, preventing the successful completion of the sort. This message does not necessarily mean that MFX was responsible for the error. If, for example, the error is in the COBOL Input or Output Procedure of an invoked sort, WER999A will appear. WER999A indicates that MFX got control after the error, printing this MFX message.
The documentation accompanying WER999A varies with the error involved. It may consist of a standard system dump (SYSUDUMP or SYSABEND) and/or an MFX-generated SNAP dump. The MFX SNAP is formatted very much like a SYSUDUMP. In debugging the SNAP, care must be taken to avoid reliance on the PSW AT ENTRY TO SNAP and the general registers.
A SNAP dump produced through the MFX DEBUG PARM or with a W-abend (that is, WER999A UNSUCCESSFUL SORT xxxW) is only useful to a sort analyst at Precisely Support. See Before Contacting Precisely Support later in this chapter.
