The subroutine package TREEPAK is designed to interface a PL/I
program with a graphic display unit, allowing display, creation and
manipulation of tree structures, while providing the user with a
graphic representation of the tree. The package is implemented under
IBM System/360 using the IBM 2250-1 graphic display unit as the primary
input/output device. Facilities include creation of trees from
the alphanumeric keyboard and cards, adding and deleting subtrees in
existing trees, and saving and retrieving trees. Trees may be passed
between TREEPAK and the user written main program. An implementation
of the Wang Algorithm is given as an example application program.
