<<What advantages can the Win95/NT version of GNAT offer me compared to
DOS GNAT?

In particular, will the Windows version allow me to draw pictures using
line/circle/box primatives in actual screen-windows with scrollbars and
menus? If so, how - is it easy?

Also, does the DOS version allow multiple tasks?>>

The DOS version allows tasks but only within a single Windows process.
The NT version maps tasks to NT threads, and also allows access to
Win32 graphics capabilities, using the win32 bindings. The win32
API is pretty complex, so no, I would not characterize this as easy!

The windows version also allows interfacing to other windows stuff.
