FALSE

FALSE is a predefined constant to be used in boolean expressions.

Syntax

FALSE

Usage

FALSE is a predefined constant that can be used as a boolean value in boolean expressions.

The FALSE constant is equal to 0 (zero), as an INTEGER type.

For backward compatibility reasons, the FALSE constant is not of type BOOLEAN. This can have impact on data conversions, for example when using a JSON API where true / false are expected.

TRUE and FALSE are typically used as return values of functions that give a boolean result.

Example

MAIN
  DEFINE odd BOOLEAN
  LET odd = is_odd(125763)
  IF odd THEN
     DISPLAY "Number is odd."
  END IF
END MAIN

FUNCTION is_odd(value)
  DEFINE value INTEGER
  IF value MOD 2 = 1 THEN
     RETURN TRUE
  ELSE
     RETURN FALSE
  END IF
END FUNCTION
