XES COMMAND LANGUAGE MODE
More You can have as many sets of coordinates for a line as desired.
If the value for X 1 is omitted, the printer uses the x-coordinate
from the current graphic position. If this line is the first graphic
image drawn in the window, the x-coordinate of the window
origin is substituted for the x-value.
If the value for Y 1 is omitted, the printer substitutes the y-
coordinate from the current graphic position. If this line is the
first graphic drawn in the window, the y-coordinate of the
window origin is used as the y-value.
If the value for X 2 is omitted, the printer repeats the first x-
coordinate, X 1 . For all succeeding coordinates, the x-coordinate
of the preceding point is used as a default if a new value is
missing.
If the value for Y 2 is omitted, the printer repeats the first y-
coordinate, Y 1 . For all succeeding coordinates, the y-coordinate
of the preceding point is used as a default if a new value is
missing.
Example To create the line in figure 2-27 which is five pixels thick and
draws four lines between five pair of coordinates, enter:
