  13. Is there any easy way to tell if a field exists without a dialog coming up?
  14. I guess I want a command like this:
  15.  
  16.   if foo is a bg field then
  17.     blah blah blah
  18.   else
  19.     put "Unknown field " & foo & "... Skipping to next record" into msg
  20.   end if
  21.  
  22. Thanks a bunch, gang!
