I take it all back! :-)

We've lead a sheltered existence here and it's been too long ago to still feel 
that
sharp sting of an application which has been modified by X prior programmers 
(most
fresh out of school) each following their own brand of "standards" if any.  
You're
right, a holy mess it can be.

Personally and professionally, we wouldn't touch such an application and shoot
right towards replacement.  And if any competitor should disagree and want to
tackle the job, they can have at it.....it'll keep them off the streets for a 
while
;-)

As I mentioned in my posts, I wasn't picking on you.  Your post just happen to 
fall
after another "news" piece about the cost of Y2K.

One of the things we did was to start with the SCNALLSRC (Scan all source) 
command
in the QUSRTOOLS, modified it, and automated a process to look for the usage of
date related fields.  By doing a DSPFFD of all of the physical files into an
*OUTFILE, we used that as a driver and looked for every occurrence of a fields
usage, output that to a file which we sorted by field name/program name.  This 
gave
us our hit list.  We are really strict about field naming conventions so we 
could
do some pretty good filtering.  The programmer was given the source listing and 
the
hit list sorted by program/field and showed statement numbers.  Helped out a 
lot.

Good luck.
