EDIT: I'm being stupid, read my own reply below.
I've been writing some test code to learn how AGS implements OOP. So my very first struct in AGS looks like this:
struct List
{
protected int arrSize;
protected String list[];
protected int count;
import writeprotected attribute int Count;
import attribute String Items[];
import int Add(String value);
import function Remove(int idx);
import int get_Count();
protected import function set_Count();
import String geti_Items(int idx);
import function seti_Items(int idx, String value);
protected import function ExpandArray();
};Obviously, it's a try to implement a Collection object in AGS that is a bit more dynamic than to work with arrays (the code works fine BTW).
My question is why I'm required to implement the set_Count() function for a writeonly attribute, I understand that within the struct I can use this.Count but in my case I only use the count (with lowercase letters) to change the Count property. In my opinion, the set_Count() function should be voluntary to implement, AGS should be smart enough to just throw a runtime error if I ever use this.Count = someValue in my code if I haven't implemented the set_Count() function.
Another question related to my implementation above: This List struct only accepts strings. Is there any generic type in AGS that can accept any value, either a number or a String, such as an object (and I'm talking about the type here, not Room Object)?
I'm soooo sorry, I'm being stupid, AGS also have a readonly, that's obviously the one I should use.
My second question remains though, do AGS have a generic data type?

No, that's one of the big limitations of this script.
It has no generic data type, no C#-like generic functions, nor C++ like templates.
It does support extending a struct, and up-casting from child to parent struct pointer (if these structs are declared as "managed"), but does not support down-casting at the same time (latter may be added in AGS 4 in theory, where we implemented some form of runtime type detection).
EDIT: Duh, I can't even read today, you said there were no generic data type, sorry. Please ignore this.
I wasn't referring to generics as in C# or C++ templates, I meant more like a generic or variant type, like System.Object in .Net
