code:

---

 
Function test()
  Open(some_file)
  If @ERROR 
    Exit @ERROR
  EndIf
 
  :
 
  do stuff to the file & Close()
 
  :
 
  $test = $answer1,$answer2 ; return an array
 
  Exit 0   ; <= is this necessary, or recommended?
 
EndFunction

Finally, when a function can return Yes, No, or Fail, is "1", "0", and "-1" a reasonable representation of the Yes, No, and Fail values?

Thanks for the comments & feedback.. I kind of know what's right in my head, but - if I'm going to write a UDF that might be used by others, I'd like to make sure I follow the same path as everyone else (within reason ).
