== Syntax ==

col[ ]

== Semantics ==

In combination with the array, the programmer can specify whether allocation is row or column major. This allocation information is provided in the allocation type.

== Example ==


 var a:array[Int,10,20] :: allocated[col[] :: multiple[]];
 ((a#1)#2):=23;
 (((a :: row[])#1)#2):=23;

Where the array is column major allocation, but the programmer has overridden this (just for the assignment) in line 3. If one array of allocation copies to another array of different allocation then transposition will be performed automatically in order to preserve indexes.
