Passing unknown number of referenced variables to a function

[Geoff Canyon]

For the true kluge choosy kluge lovers choose, create the function with 
more input variables than you will ever need, and then pad calls to the 
function with dummy variables as needed. You need an additional 
parameter to identify the number of non-dummy arguments, like so:

function add10 pCount, at pVar1, at pVar2, at pVar3
   repeat with i = 1 to pCount
     do ("add 10 to pVar" & i)
   end repeat
end add10

Then these both work:

get add10(3,myVar1,myVar2,myVar3) -- all three are valid
get add10(1,myRealVar,x,y) -- x and y are dummies

You could also skip the count and just increment all the variables, 
obviously.
