Don't use globals. Globals are baaad.

Use the multi dimensional array approach as Jochen suggested. You may return an array which contains other arrays or plain variables.

Here is a simple example:
Code:
$RETURN=udfFruitColours()

$FruitList=$RETURN[0]

$ColourList=$RETURN[1]



For $i = 0 To Ubound($FruitList)

	"A "+$FruitList[$i]+" is "+$ColourList[$i] ?

Next

 

Function udfFruitColours()

	Dim $asFruit,$asColour

	$asFruit="Lemon","Strawberry","Lime","Banana"

	$asColour="Yellow","Red","Green","Yellow"

	

	ReDim $udfFruitColours[2]

	$udfFruitColours[0]=$asFruit

	$udfFruitColours[1]=$asColour

	

	Exit 0

EndFunction



Exit 0
