Re: Error messages: source code line is blank

Mary,

I checked for off by one thusly. I ensured that there were valid
statements on lines 103 and 105. The error message for line 104
still printed blank for the source code line.

I also made sure that line 104 was the actual line with the error,
in this case a true undefined procedure reference.

This is no show stopper, just a chronic inconvenience when trying to
debug. Thank you for checking into it.
