Hi All,

I have (though all of these posts) been trying to follow the instructions for
GENERICS on this page:http://wiki.lazarus.freepascal.org/GenericsThis page
makes no reference to SPECIALIZE keyword. That is where I got the reference to
type "T".Can someone please provide an example of using a TList and an object
(as in my code) so that I had access to a custom Tlist with the Sort
procedure... which is really my reason for needing this.

Okay, except that Island is not meant to be an integer. See here:
line 88Tmap_detail = Object FTerrain : Terrain_type;
FTerrain_char : char; Fdescription : description_type;
Fx, Fy, Flocation_number : integer; Fexits :
exit_type; end; // The Island class definition Generic
TIsland<T> = class Items : array of Tmap_detail; public constructor
Create(AList: TList); procedure Add( Value : Tmap_detail ); end;
