Function to set a local variable

Hi folks. I might be missing something very simple. When I use a function, normally I return a value that is then used locally. For example
Code: Select all
put square_it(6) into tSquare
function square_it pNumber
return pNumber * pNumber
end square_it
tSquare now has value 36.
Now what I am looking for is to say:
Code: Select all
get square_it(6, tSquare)
function square_it pNumber, pVariable
...
end square_it
After calling it, the local value, tSquare, should automatically have the value 36. Assume it has not been declared as global, local, or script local.
Any ideas?

See the "@" operator in the Dictionary for handling arguments by reference, e.g.:
Code: Select all
function square_it pNumber, @pVariable

Hi Kaveh,
Any ideas?
Yes, do not use a function but a handler and do not use variables, they HAVE to be declared somehow and somewhere!
Use a custom property instead like this:
Code: Select all
command square_it pNumber
set the cNameThisPropertyAsYouLike of this stack to pNumber*pNumber
end square_it
But maybe I do not really understand what you are looking for...
Best
Klaus

Thank you both for the fast replies. Richard, you got it. I had no idea about this but it works! Thank you so much.
And Klaus thanks for reminder about custom properties which have saved the day many times!
