Most installations provide a program to assist in drawing stylized diagrams which can illustrate structures, relationships and flows. The DRAUGHTSMAN program was written to overcome shortcomings in earlier examples of this type. Firstly, drawing movements can be specified in relative terms, and positions on the diagram can be labelled, giving the advantages of flexibility for subsequent modification equivalent to those of relative addressing over absolute addressing in programming. Secondly, the program will, unless instructed otherwise, make its own selection of a reasonable paper size and orientation. Thirdly, the inclusion of text within boxes and along lines is flexible and unrestricted; this is combined with a wide range of drawing styles. A specification of the drawing language is given and an illustrative example provided.
