d These are the routines that can be used for a program that plots data. They are containied in the DO LINK library. These request ,the device to be used for plot output at run time, and thus permit the programs to be written, and then run to produce plot output to the CRT, Line_Printer, tectronix 4006 or 4014, and the HP_plotter. X  TEK calls SET . see INFO SET, CLEAR . see INFO CLEAR, clears the "screen". MOVE(IX,IY) . see INFO MOVE, moves the "pen". LVEC(ITYP,IX,IY) . see INFO VEC, writes a line. SEND . see INFO SEND HAFTON(IN,IX,IY) . xHARD . see INFO HARD, to end each plot. WRTCHR(IX,IY,fort_array) . see INFO WRTCHR, writes an array of chars. @WRTSTR(IX,IY,char_string) . see INFO WRTSTR, writes a CHARACTER string.  JJPANY(MODE, ITYPE, XPOS, YPOS) . see JJPANY, general plot routine.  This supports 0.0 thru 1.0 XPOS and 0.0 thru 1.2 YPOS 4 and is the lowest level plot routines.
