boolean

comment

Booleans might be true or false, "common.j" variables TRUE and FALSE were added to allow you to use them, but it is not a good idea to do so. Using true is faster than getting a value of variable TRUE.

Comparision expresions ==, <=, <, >, >=, != return boolean.

Statements if, elseif and exitwhen take boolean as argument.
