RETURN
RETURN xResultadoEnds a function and provides its result to the caller.
Overview
RETURN transfers control back to the caller. Its value follows the function contract: Nil, .T., strings and arrays have different meanings to callers. RETURN inside a loop ends the entire function; Exit ends the relevant loop. Early returns do not replace cleanup. This example adds a small static function with a numeric return and distinguishes returning from printing. (Sources: refs. 1–1.)
