t

t  --  a logically true value.

Syntax

t

		

Returns

t

Description

The special object, t, is a logically true value which has no other meaning. All Gamma objects other than nil are logically true, but only the special object t is the logical negation of nil. t is created by a call to not(nil), or by reading the symbol t.

The predicate true_p explicitly tests for the value t. However, in all conditional statements, any non-nil value is considered to be true for the purpose of the test.

Example

    Gamma> x = 3;
    3
    Gamma> x > 2;
    t
    Gamma> x == 3;
    t
    Gamma> !nil;
    t
    Gamma> 10 < 25;
    t
    Gamma>
