Hi, Dean

Here's my Nth response, albeit a little late. We're a fairly good-sized shop (megalomania arising here?), with 400's of various sizes at 13 sites around the country. We've begun using ALDON's CMS only in the last year and a half, as well as Hawkeye's Pathfinder cross-reference tool. They both save our lives on a regular basis.

We've long had the standard of not using LVLCHK(*NO). AFAIC, LVLCHK(*YES) gives protection we ignore at some peril. Also, I think it's more work than it's worth to keep track of what uses *NO and what uses *YES. Exceptions just make our work harder.

Recompiling all programs that use a file can be a big deal. We have a file on which, it seems, 100's of objects depend. It's our title order master. All our business revolves around this file. Changes to this file would result in days of effort to get all the correlative stuff done. Nonetheless, we'd do it—it's just part of the job, right?—but not without painstaking justification first. And we'd use the CMS tool and all the dependency skills it has. In fact, we are doing this with our Year 2000 effort.

The only time we use LVLCHK(*NO) is in very limited situations, to facilitate testing only, and with full knowledge that there's more work to do. IMHO, this attribute is too easily abused (no accusations here :-))

With you
