type Boolean = (False, True); { built-in type }
True is one of the two Boolean values and is used to
represent a condition which is always fullfilled. For example, the
expression 1 = 1
always yields the value True. It is
the opposite of False. True has the ordinal value 1.
True is defined in ISO 7185 Pascal and supported by all known Pascal variants.
program TrueDemo; var a: Boolean; begin a := 1 = 1; { yields True } WriteLn (Ord (True)); { 1 } WriteLn (a); { True } if True then WriteLn ('This is executed.') end.
