Passing parameters by reference

[Pete]

That would work but the complication is that the function is already
returning true or false to indicate whether it changed the input or not so
I can do something like:

if modified(tvar) then
   --do something
else
  --do something else
end if

If I change it to return the result of it's operation on the input, I'd
have to do something like

put modified(tvar) into tTemp
if ttemp<>tvar then
  --do something
else
  --do something else
end if

That works just fine but just seems more elegant to be able to do it the
first way, especially since most of the time I'm calling the function with
a simple variable as the input, not an array element, and the first way of
doing it works just fine.

Anyway, there's multiple ways to work around the problem until LC is fixed
to allow array elements to be passed by reference (hopefully!)

Thanks,
Pete
