CHAR PLOT is a routine which enables one to use the CalComp plotter as a versatile output device. It is presently available as CHPLOT BIN (English CHAR PLOT) on tape MS 3. The program CHAR PLOT is normally called by a PUSHJ P, PL:OTC with a code representing a command or character (as defined in Appendix I) in accumulator C. Upon calling, the routine will either plot a character or line, or perform an internal control function. A O code initializes the routine, erasing any unexecuted (buffered) commands.
