SUMMARY
The Apple LaserWriter does not support Macintosh "regions."
Page 85 of the "Programmer's Introduction to the Macintosh Family"
(published by Addison-Wesley, 1988) states "You should never use
regions with any image that will be printed. The LaserWriter's
firmware does not support regions."
This information applies to Microsoft QuickBASIC Version 1.00 for
Apple Macintosh Systems. The WINDOW OUTPUT #n statement in QuickBASIC
cannot be used to redirect regions to the Apple LaserWriter printer.
You can define and manipulate regions with the following MBLC
routines, which are built into QuickBASIC:
NewRgn OpenRgn CloseRgn FillRgnHdl PaintRgn
FrameRgn PtInRgn DiffRgn InsetRgn RectRgn
InvertRgn SectRgn MapRgn DragGrayRgn SetEmptyRgn
EmptyRgn SetRectRgn EqualRgn OffsetRgn EraseRgn
FillRgn CopyRgn DisposeRgn XorRgn
These MBLC routines are documented in Appendix E.10 on Pages 471 to
497 of "Microsoft QuickBASIC for Apple Macintosh: Language Reference."
