EA - Edge Rectangle Absolute
EA X, Y[;]
X ; X coordinate of opposite corner for the rectangle
Y ; Y coordinate of opposite corner for the rectangle
• X and Y coordinates are absolute coordinates in current units.
• Plots the rectangle formed by the current position and the opposite corner specified by X and Y.
• After plotting, the cursor returns to its point of origin, and pen up/down status remains as selected.
• Plotting is performed whether the pen is up or down.

ER - Edge Rectangle Relative
ER X, Y[;]
X ; X coordinate of opposite corner for the rectangle
Y ; Y coordinate of opposite corner for the rectangle
• Coordinates are relative to the current position in current units.
• Plots the rectangle formed by the current position and the opposite corner 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.
