=={{header|Component Pascal}}==
An arrays in Component Pascal are started from zero index. No DISPOSE-like procedures because of garbage collection.
<lang oberon2>
MODULE TestArray;
(* Implemented in BlackBox Component Builder *)
IMPORT Out;
(* Open array *)
PROCEDURE DoTwoDim*;
VAR d: POINTER TO ARRAY OF ARRAY OF INTEGER;
BEGIN
NEW(d, 5, 4); (* allocating array in memory *)
d[1, 2] := 100; (* second row, third column element *)
d[4, 3] := -100; (* fifth row, fourth column element *)
Out.Int(d[1, 2], 0); Out.Ln;
Out.Int(d[4, 3], 0); Out.Ln;
END DoTwoDim;
END TestArray.</lang>
=={{header|Factor}}==
Factor doesn't provide any support for easy access of 2d arrays. But since factor's written in factor, we can just add it and it's just as good :)
