Editing MAD (programming language) (section)

===Arrays and matrices===
* There is no limit on the number of dimensions.
* Negative and zero as well as floating-point subscripts are allowed.
* Matrices are storied in consecutive memory locations in the order determined by varying the rightmost subscript first.
* Matrices may be referenced using a subscript for each dimension, NAME(s<sub>1</sub>,s<sub>2</sub>,s<sub>3</sub>), or using a single subscript, NAME(s<sub>1</sub>).
* Input-output lists, VECTOR VALUES statements, and some subroutines allow the use of block notation, which has the form A,...,B or A...B, which is a reference to the entire region from A to B. inclusive. In terms of a vector, A(1)...A(N) would be A(1), A(2), A(3), ..., A(N).
* There are facilities that allow changing dimensions at run-time; permitting the programmer to vary the location of the initial element in an array within the overall block which has been set aside for the array; and allowing an arbitrary storage mapping to be specified.
