Beginning at the current pen position, a series ofvectors is drawn by moving the pen 100 units
to the right, up 100 units, left 100 units, and finally down 100 units. The same figure could have
been drawn at any screen location by first positioning the pen to the desired starting point
before sending the drawing sequence.
ASCII RELOCATABLE FORMAT. The ASCIIrelocatable format allowsyou to use a relocat-
able origin to be added to the incoming X and Y coordinate values. The resultant values are
then treated as absolute coordinates by the terminal. The relocatable format allows you to use
absolute data as if it were incremental by merely changing the relocatable origin. For
example, symbol elements specified in absolute coordinates can be drawn in different locations
as shown in the following example.
Examp1 e: Draw a resistor symbol stored in absolute coordinates at screen locations 50,100
and 200,100.
