This package provides array data structures in (La)TeX, in the meaning of the classical procedural programming languages like Fortran, Ada or C, and macros to manipulate them. Arrays can be mono or bi-dimensional. This is useful for applications which require high level programming techniques, like algorithmic graphics programmed in the TeX language.

The package is now superseded by the package, which has the same specification but is less error-prone.
