Hi Robert

>I would like to know where do you stand on using logical versus numerical variables .

Within VFP I don't think it really matters one way or the other. I like to use logical values for return because you can then include them in IF conditions...

IF Myfunc()
  *** Do something
ELSE
  *** Something else
ENDIF

However, as you as you say, it is sometimes nice to be able to return more detailed values and I have used -1 (Error), 0 (False) and 1 (True) successfully too. When you start looking outside VFP you will realize that most servers do not implement Logical values as VFP does, and you are forced to use numeric values anyway.

So I really odn't think it matters one way or the other. Use whatever suits your personal needs and style.
