-- Used to embed an 'if' test inside an expression.

--

-- Parameters:

-- # ##test## : an atom, the result of a boolean expression

-- # ##ifTrue## : an object, returned if ##test## is **non-zero **

-- # ##ifFalse## : an object, returned if ##test## is zero

--

-- Returns:

-- An object. Either ##ifTrue## or ##ifFalse## is returned depending on

-- the value of ##test##.

--

-- Example 1:

--

-- msg = sprintf("%s: %s", {

-- iff(ErrType = 'E', "Fatal error", "Warning"),

-- errortext } )

--

-- returns ifTrue if flag is true, else returns ifFalse

end if
