Jezz, might this be a good reason to use SQL? Nah, better to keep just
compiling the whole table into every program.

That's like playing Russian Roulette, except there's 3 rounds in the
cylinder instead of one.

Subject: Running with LVLCHK *NO in production

Hi everyone,

A customer just had a big emergency today. They ran a program that had
been run in many years and it completely ruined their part master file. I
investigated and found that the program had last been compiled in May 1998
and the part master file was last created in June 1998 with LVLCHK(*NO).
Of course, the file layout had clearly changed and when the program ran it
happily destroyed every record in the part master file.

My question is: is there any good reason to use a file in production with
LVLCHK(*NO)? If a level check had happened, this whole fiasco would have
been avoided. I didn't write the software (happily) and I can't think of
any reason why they would have built this file with LVLCHK(*NO).

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
