I guess I don't understand the concept of false. I wanted to set flag in my script manually. At first I flag = true and all was well. later I ran a test if flag But when I set the flag to false (flag=false), the script doesn't work correctly. If test before the "if flag" don't evaluate correctly. Work around is easy enough, just use a string or number for the variable. But I think I'm missing something fundamental here. As you may have already guessed, I don't have a programming background. Thanks

I think something else is going on. Even if I use a string, the script doesn't work with my equivalent of false. I need to recheck the logic.

False and if are probably as simple as you think they are... irb(main):001:0> foo = false => false irb(main):002:0> if foo; puts "I'm foo!"; end => nil irb(main):003:0> foo = true => true irb(main):004:0> if foo; puts "I'm foo!"; end I'm foo! => nil irb(main):005:0> Chances are you're doing something else wrong... What does, "The script doesn't work correctly" mean? Is an exception thrown, are you getting incorrect results? Code samples are also helpful. MBL

(The first responded didn't see my CORRECTION, and he was correct in assuming something else was wrong). Being new to Ruby I was surprised that the missing card (which needed to be read) didn't cause an error. After the first posting I simplified the problem and realized it wasn't the false that was causing the problem. Later I sorted out what was really going on. Thanks for responding.
