Generic array

[AncientyHacker]

So I'm playing with this newfangled generic feature.

Kinda cool, you can paremeterize the type of the array elements:

MultiArray<Ty> = record
Items: array[ 1..100 ] of Ty;
end;

Next thing, I'd like to paremeterize the index type:


MultiArray<Ty,Inx> = record
Items: array[ Inx ] of Ty;
end;

... but no joy, the compiler complains about that. It wants an already defined ordinal type. Sigh.

Why would there be such a severe restriction like that?

Dude - Both '<' and '>' are reserved characters for 'less than' and 'greater than', respectively. Something any 'Ancient Hacker' should know. LOL

No roo,

he has a valid point.
This is the syntax for Generics.

AncientyHacker, Generics are more suited for OOP.
arrays are really not suited for this. You can solve your problem with TList<T> though.
