Hi Sergey:

>Yes. You would check for exactly value 3 this way.

lnValue = 22
IF BITAND(lnValue, 3) = 3
  WAIT WINDOW NOWAIT "Yes, it's 3"
ELSE
  WAIT WINDOW NOWAIT "Not 3"
ENDIF 

Right. Penny dropping even further <s>. You and Hilmar have helped me a great deal with this and I really appreciate it.

Best
