This Paper describes on a language for the treatment of graphs as a new type of data. This language is called Graphic Programming Language One (GPL/I) and is defined as an extension to PL/I. It consists of two kind of statements, GPL/I statements and PL/I statements. A GPL/I statement is translated into PL/I statements by means of precompiler (GPL/I Compiler) which was developed on IBM 370/165. In this compiler, graphs are treated as a one-directional list and new graphic operations are defined such as point and/or line deletion or insertion, graph complement, union and intersection, As an example, a sample program to get one spanning tree of a given graph is shown.
