Howard:
You bring up a very good point. I was thinking as I followed this thread, that
when I supported a large group of Cobol programmers that all of the posters
thus far had a valid point. At one point we too said there was no need to use
the display, or something we saw once in a while, Exihibit-Named to print the
error data. But we also realized that there ARE some conditions that perhaps
cannot be easily detected in an edit and decided that it was better to capture
the data when it occurs rather than to have to re-create it later since enough
of the information may already be available to resolve the problem. Of course
it should not be used indiscriminently. One condition I remember seeing was
assembling a record from multiple indices of a highly normalized database which
would be difficult to detect in an edit.
Just my .02 since I am partied out and decided to check emails.
Just a thought
