ER - Edge rectangle relative
ER X, Y[;]
X ; X coordinate of opposite angle for the rectangle
Y ; Y coordinate of opposite angle for the rectangle
• Coordinates are relative to the current position in user units or graphics units.
• Plots the rectangle formed by the current position and the opposite angle specified by X and Y.
• After plotting the cursor returns to its point of origin.
• Plotting is performed whether the pen is up or down.
• When scaling has been performed, the rectangle is plotted in user units.
• Also, when scaling has been performed, the values for X and Y are real numbers.
• When there is no scaling, the rectangle is plotted in graphics units.
• When there is no scaling, the coordinate values for X and Y are integer numbers.
