Global functions, possible feature?

I use fastloops to do an approximation of this - start a loop 1 times with parameters in global values, and then read the result off another global value (acting sort of like registers, or pass-by-reference values).

Yeah I do fastloops to do this aswell. Sometimes using global values as variables, sometimes using alterable values of objects. It's a little different but works pretty well.

Same here, but in combination with the string parser/tokenizer objects. The first element being the loop name and the rest being parameters. An event calling a function might look something like this:

+ On event
- Set Parser to "setCharPos" + "," + Str$(actor value) + "," + Str$(x value) + "," + Str$(y value)
- Start Loop 'Get Parser First Element'
(Note: The parser delimiter of course being ",")

The upside being setting all the parameters with just one action, the downside would be that reading from the parser object might be a bit slower.

Also, I'm guessing setting up functions will be an option in Fusion 3. It will even be possible to create your own extensions within the program.

I started doing this. It gets a bit tricky if you want nested function calls. You'd want some sort of stack data structure to do it properly.
