Hello, Scott.

Actually, that makes perfect sense.

What I'm wanting to do is this: Telegard BBS has a bit setting to make the user 
"hidden" when calling, so that user doesn't show up in the "who's online" and 
"today's callers" bulletins.  I have a DOS program that I use to do it for my 
board but with the board being OS/2 native and the DOS program takes a few 
seconds to activate.

Here's the part of the Telegard structures that I'm dealing with:

=== Cut ===
 userflag=             { USERS.DAT user flags }
  (
     newusermsg,                              { sent newuser message }
     clsmsg,                                  { clear screen before messages }
     flinput,                                 { full line input }
     hotkey,                                  { menu hotkeys active }
     pause,                                   { pause }
     novice,                                  { user is at novice help level }
     hiddenlog,                               { not displayed in call/online 
listings }
     hiddenlist                               { not displayed in user listings 
}
  );
  userflags = set of userflag;
=== Cut ===

So what I'm wondering is how would I set those two bits ("hiddenlog" and 
"hiddenlist") on?  I understand how sets work now, but I'm not sure how I'd 
turn the bits on and off.

Thanks for your help in this.  Since my car accident last year, it can be hard 
for me to wrap my mind around certain concepts after my concussion. :)

Later,
Sean
