Sry, I know I've still to learn a lot about structs/pointer/etc. Somewhen I will go through a good book... till then there are questions like the following, for some of you sounding stupid or at least obviously/simple ... anyway:

--------------
this works, native:
Code:
function demonstration(var my_own_var) {
	...
	my_own_var = 37;	// do whatever I want with it, nobody cares
	...
}
...
	var number_for_everyone = 1;
	demonstration(number_for_everyone);
	...
	number_for_everyone = 7;
	demonstration(number_for_everyone);
	...
	demonstration(number_for_everyone);
...


this not:
Code:
function demonstration(ANY_STRUCT my_own_struct) {
	...
	my_own_struct.x = 37;	// do whatever I want with it, nobody cares?
	...
}
...
	ANY_STRUCT struct_for_everyone;
	struct_for_everyone.x = 1;
	demonstration(struct_for_everyone);
...

Compiler: Syntax error: can not push STRUCT@69

Why?

I only know this way round:
Code:
function demonstration(ANY_STRUCT* temp_my_own_struct) {
	ANY_STRUCT my_own_struct;
	my_own_struct.x=temp_my_own_struct.x;
	...
	my_own_struct.x = 37;	// do whatever I want with it, nobody cares! 
	...
}
...
	ANY_STRUCT struct_for_everyone;
	struct_for_everyone.x = 1;
	demonstration(struct_for_everyone);
...


Any better solutions?

At least a possibility to copy the whole dataset of a struct into a new one. Like vec_set but for every struct? (okay, I could write an own function or define for it...)
