Maybe I'm living with different people than you or others in this list
are with. :)

It's just been my experience that these are not issues to contend with. 
If a user wants data off the 400 they ask which file to get, we tell
them.  We may even set up logicals to make it easier.   We don't have
users accessing information without prior knowledge or consent.  We
"jealously guard" our files more for security than anything else.  Heck
as far as I'm concerned any user can have whatever data they are
authorized to get.  We'll even help them get the data.  But to have a
user browse around the system and grab whatever suits there fancy? I
don't think soooooo.  I guess it all depends on the shop rules.

I know with all that we have going on, little details slip by.  If you
check my original post, we use the IS and UF versions of the same file
for the very reasons you stated. WOW! Agreement! ;-)

have a good one
