I have a cursor operation that prints a report for a list of people.
It is so enthusiastic that it continues to print after the end of data is reached. Unfortunately it duplicates the final report and seems to be in an endless loop which requires an inelegant exit from the program.
When I traced the operation I can confirm that the value for SQLCODE changes so that it is no longer 100. That should interrupt the:
WHILE SQLCODE <> 100 THEN
Thinking that I might not have been talking loud enough, I reminded the program again that 100 was reached with the following command, which was also ignored:
IF SQLCODE = 100 THEN
GOTO lfinish
ENDIF
ENDWHILE
LABEL lfinish and so forth.
Sometimes I figure out what is not working while I attempt to document it for someone else.
Not this time...
Can you suggest how I can help the operation to stop when it is complete.
Best R:egards,
Randy Peterson
