Actually neither OPEN nor OPEN AS are appropriate for a window-oriented
user interface. What you need to be able to do is grab a file from the
workbench and drop it into the program window. You should also be able to
pick up a file and drop it into a program icon to start the program with
that icon as "input".

To do this you would need only (only?) add a new message "new file" to go
along with "resize" and other windowing messages. When the program gets
that message it can put up a requestor asking whether you really mean to
discard the old file (presuming it can only deal with one file at a time)
if there is one and then open the new one.

This would also provide a hell of an incentive for people who write software
for this beast to write well-behaved workbench programs (at least they'd
have to open one window in the WB even if they used their own screen) instead
of PC-ware.

How about it, C=Amiga?
