You might want to try my ERROR_MESSAGE routine. It was
designed *exactly* for this reason. I wanted sensible
error handling *AND* I wanted traceback information
to tell me the line number of the error:

All of your code will remain the same, and your CATCH
error handler, which previously looked liked this:

CATCH, error_status
IF ( error_status NE 0 ) THEN BEGIN
CATCH, /CANCEL
MESSAGE, !ERROR_STATE.MSG, /CONTINUE
RETURN, FAILURE
ENDIF

Will now look like this:

CATCH, error_status
IF ( error_status NE 0 ) THEN BEGIN
CATCH, /CANCEL
ok = ERROR_MESSAGE(/Traceback)
RETURN, FAILURE
ENDIF

Cheers,

David
