Line 151: =={{header\|Metafont}}== Metafont has the type <tt>boolean</tt>; a boolean variable can be <tt>true</tt> or <tt>false</tt>. Using non boolean values (or expressions that do not evaluate to a boolean value) results in a recoverable error; by default, any non-boolean value is interpreted as false. =={{header\|Modula-3}}== Similar to [[Ada]], Modula-3 has a built-in <tt>BOOLEAN</tt> type defined as <lang modula3>TYPE BOOLEAN = {FALSE, TRUE}</lang> =={{header\|Objective-C}}==
