Advanced programming aids in PROGRAPH

ABSTRACT

The graphical functional language PROGRAPH is briefly described, followed by a more extensive discussion of prograph development facilities. In particular, the PROGRAPH editor/interpreter is described, which allows prographs to be simultaneously constructed and executed, using sophisticated graphics in interactions with the user. The micro-PROLOG implementation of the editor/interpreter is described, and the reasons are discussed for choosing Prolog as the implementation language for PROGRAPH on small computers.
