Computer graphics at a large IBM installation

Heavily used plotter- and computer-independent graphics facilities are supported for a large IBM batch and time-sharing installation. JCL-selectable plotter drivers present a common interface to the supported graphics packages. Their selection can be made at linkedit or at execution time. Driver output can go to line printers, pen plotters, electrostatic plotters, microfilm recorders, or terminals for plotting; or driver output can go to OS datasets for later post-processing. The drivers self-initiate, their output is self-identifying, they self-terminate at either normal or abnormal job end, and they provide for automatic accounting. Extensive documentation and user support is supplied.
