INTERACTIVE LINEAR PROGRAMMING PACKAGE
             --------------------------------------

                            ABSTRACT
                            --------

This package solves simple linear programming problems of any
form, i.e. maximization or minimization, "<=" or ">=" or "="
constraints in any order are accepted. All problem parameters can
be edited and modified; variables and constraints can be added or
deleted; type of constraint and type of objective function can be
altered. Solution of problems can be traced through iterations in
several formats. Output includes primal and dual solutions, the
optimal Simplex tableau, as well as sensitivity analysis on
objective function and right-hand-side coefficients. Input and
selection of output options is interactive. 

The package is completely self-documenting, i.e.  specific
instructions are available whenever input is required from the
user. The package does not require APL terminals for input or
output. A write-up is available with the package which includes
a sample terminal log and interpretation of output formats.
