What is a correct boolean expression?
Posted by LX&R Bacherikov 17 Aug 2007 20:13
Here is the right description:

1) A, ..., Z, TRUE, FALSE - are correct boolean expressions;

2) if x and y are correct boolean expressions, then the correct boolean expressions are also:
  (x);  NOT x;  x AND y;  x OR y  (maybe, with some extra spaces).

It's not completely true, some spaces also may be missed as in example.
