yep! i realized this when i was going back thru the code cleaning it up and
letting the other side of my brain wander about in its own world ;)

i was sending the pointer to field's contents ;)
[time passes]
well, i thought i was... my KeyOf routine does a cast using
PTLERec(Item)^.catnbr
but my (TLE) compare is apparently only sending the pointer to the catnbr string
because the cast there is simply
PString(Key1)^
and
PString(Key2)^
the only place i understand that my (TTLEColl) compare is in play is in
If NOT Search(KeyOf(Item), I) OR Duplicates Then // Item valid
from the TTLEColl.Insert routine override that i posted previously... that
Insert routine is taking a pointer to an entire record...
so now i'm a bit confused but it has been a long day... again... :/
