(I.e. I would expect Exp(x,y) to return a number, not an array of strings)

---

code:

---

function EXP($x,$y)
	dim $x, $y, $z
	? "X = " + $x + " of type " + vartypename($x)
	? "Y = " + $y + " of type " + vartypename($y)
	$z = $x
	for $i=2 to $y
		$z = $z * $x
	next
	$err = @Error
	$errtext = @Serror
	? "Z = " + $z + " of type " + vartypename($z)
	$EXP = $z, $err, $errtext
endfunction
$result = EXP(2,3)
? ? "Results:"
for $i=0 to Ubound($result)
	? "element $i = '" + $result[$i] + "'  is type " + vartypename($result[$i])
next
