Subroutines GEORGE and DRASTC simplify operation of automatic digital plotter

F. Englel, W.H. Gray, P. J. Richard

Abstract

FORTRAN language subroutines enable the production of a tape for a 360-30 tape unit that controls the CALCOMP 566 Digital Incremental Plotter. This provides the plotter with instructions for graphically displaying data points with the proper scaling of axes, numbering, lettering, and tic marking.
