9.33 Copy (8A Hex)
Copy the rectangular region defined by the starting point (X1, Y1) and the ending point (X2, Y2) to location
(X3, Y3). There are two possible results with the command copy executed depending on the setting of the
start point coordinates and end point coordinates.
The following example illustrates the copy procedure.
Case 1 – The overlap region will superimpose.
Case 2 – The original content remains unchanged
Remark: X1, X2
