I had to ask. Can you use reference parameters in functions like C++. I am assuming you can't but anymore tools than I already have would be helpful.

Because if you can't then functions can only pass in and out one piece of data somewhat limiting there usefulness. The fact that subroutines will have to handle anything that requires two or more data pieces is a bit annoying.

So can you?

arrays are global , they hold their values inside or outside functions, so you can pass more than one value, also you could load a memblock or the clipboard with the values you want to pass, maybe even a user defined type (but not tried that...don`t take my word for it) you just have get inventive, (messy coders like me scorn structure anyway ).

I like avoiding excessive use of arrays. I always invision making them like slating stuff in stone. I don't really like using arrays indiscriminately.

Can't you use the GLOBAL command to make the variable global?

As for memblocks, it seems a bit complex for a simple problem. I'd rather just use some subroutines if necessary.

Yes, you can set a variable as global (if it is outside a function). You can use this to pass back types (as you can't currently return them from functions)
