type Boolean = (False, True); { built-in type }
False is one of the two Boolean values and is used to represent a condition which is never fullfilled. For example, the expression, 1 = 2 always yields False. It is the opposite of True. False has the ordinal value 0.
False is defined in ISO 7185 Pascal and supported by all known Pascal variants.
program FalseDemo; var a: Boolean; begin a := 1 = 2; { yields False } WriteLn (Ord (False)); { 0 } WriteLn (a); { False } if False then WriteLn ('This is not executed.') end.
