Is there any way to set a function as "global" so that it can be called from any handler in the same stack or subsequent substacks in similar fashion as global variables?

There are other ways of doing a similar thing, but this would be very useful since I'd rather not change it to an "on ..." or need to copy the same code to every handler of my program in order to use the function, and sending the function's name and parameters (as a message) just gives errors.

If it's not possible, then I'll just find a different way to make it work.

You can call a function remotely using this syntax:

put value("myfunction(param)",<script reference>)

For example, to call a function named "myFunction" with two parameters, where the function is in the second card of the stack, do this:

put 1 into a
put "dog" into b
put value("myFunction(a,b)",card 2 of this stack)

Why not to put the function as main stack function and call it directly?

If the function is only used in a single stack, that is what I would do too. The remote call is handy if you want to use a function from a different stack and you don't have a library in use.

put 1 into a
put "dog" into b
put value("myFunction(a,b)",card 2 of stack "otherStack")

It's as close as we get for a "global" function. If there's a library in use, then that's where I would put it instead.
