Show fii , it will be inserted relative to the value of INDEX. Again a third argument may be added to indicate the display file size and is assumed to be 2500 if omitted. ORG(X,Y) S=t« the relative origin to absolute griä coordinates X,Y All subsequent display routine coordinates will be interpreted relative to X,Y. Initially, X,Y = 0,0. POS(XFY) Positaon beam at grid coordinates X,Y. VEC (X, Y) Prom current beam position, draw a vector to grid coordinates DOT (X,Y) tut a dot at grid coordinates X,Y. DASti{X,Y) From curremt beam position, draw a dashed vector to grin c( crdinates X,Y. The dash is only effective for vectors longer than about 20 grid positions. Example: DIMENSION DF(2000) CALL SETDF(DF,I) CALL ORG(0,100) CALL POS(0,0) CALL VEC(100,0) -17- |
