You can copy a complete bitmap, or a portion of it, to the selected graphic target. The expression hbmpSource??? specifies the handle of the source bitmap or window. The expression id& is reserved for future use, and must always be set to zero. The destination of the copy operation is the window selected by GRAPHIC ATTACH. You must take care that your parameters are valid for the specified bitmap, or the results of the operation are undefined. The first form of the GRAPHIC COPY statement copies the complete bitmap, positioning it at (0,0), which is the upper left corner of the destination. The second form of GRAPHIC COPY also copies the complete bitmap, but positions it at the point specified by the parameter (x!, y!). The third form copies a portion of the bitmap, specified by x1,y1 as the upper left corner and x2,y2 as the lower right corner. It is positioned at the point specified by the parameter (x,y). You must use care that your parameters are valid for the specified bitmaps, or results of the operation are undefined. If the style parameter is included, it is one of
