Checking whether a variable is false, is the same as checking if it's zero.
Program example; Private int b = false; Begin // comparison with the constant FALSE if(b == false) say("b was FALSE! so b==0"); else say("b was not FALSE! so b!=0"); end // checking the integer itself if(!b) say("b was false! so b==0"); else say("b was true! so b!=0"); end Loop frame; End End
