one liner, looks like I was wrong on both accounts:

ON mouseUp
    put "hello" into pData1
    put "world" into pData2
    put "shout" into test

    answer value(merge("[[test]](pData1,pData2)"))
END mouseUp

FUNCTION shout pData1,pData2
    return pData1 && pData2
END shout

I had a feeling merge could help but originally I had it all backwards:-(

Anyway, with this method, something like this is very flexible:

value(merge("[[custFunc]]([[pParamList]])"))

be careful to include the () around [[pParamList]]

Although no advantage in your example:

ON mouseUp
    put "hello" into pData1
    put "world" into pData2
    put "pData1,pData2" into pParamList
    put "shout" into custFunc

    answer value(merge("[[custFunc]]([[pParamList]])"))
END mouseUp

FUNCTION shout pData1,pData2
    return pData1 && pData2
END shout

clearly it would be easy to take a field/customProp/variable that contained
multiple lines with each line containing a varying number of items and use a
repeat loop to create and fill pData1, pData2,... pDataN
