I have a program which I run in blocks of 750 iterations. It seems to help to put wait states at various points (but this isn't the issue) so I have programs

OUTERLOOP.PRG
     DO setenvironment
     FOR outerloop = 1 TO 15
       DO InnerLoop
       WAIT WINDOW "Holding Outer Loop" TIMEOUT 5
     ENDFOR

INNERLOOP.PRG
     FOR innerloop = 1 TO 50
          DO realprogram
          WAIT WINDOW "pausing" TIMEOUT .5
          REPLACE doneflag WITH .T.
     ENDFOR

During one of the iterations I received a "Cannot Redefine" error. Unfortunately, my source code was unavailable to the debugger and I wasn't able to get much help from it. I rebuilt the project and recompiled the EXE, but when I re-ran the program (it started on the same record that failed) everything ran fine.

Does anyone have any information about this error?

Thanks............Rich
