Abstract:

The DF routine package allows a IBM 36067 programmer to assemble DEC 338 display files, send them to the DEC 338, control the displaying of these files, and enable light-pen service. The DF routines provide a set of elementary display file operations only they do not provide complex operations such as producing an entire graph with an axis, labels, and curve with one subroutine call. However, subroutines that allow the displaying of graphs with one subroutine call can be written using the DF routines. Other topics discussed in this report include elementary example programs, DF routine summaries, 338 display file organization and transmission format, display file assembly parameters and characteristics, and instructions for debugging programs from a TTY. A typical RUN command for a program containing calls on the DF routines and pseudo octal numbers are also discussed. Author
