Carriage Return without a linefeed on Win95?

Carriage Return without a linefeed on Win95?

[J. Marshall]

I'm using the GNAT AdaGIDE v6.21p (from GNAT v3.11) to develop some simple
little apps to run on a Windows 95 platform (and know little of Ada, as I am
still learning).  I've looked through the documentation, but can not locate
the way to output text to the screen starting at a specific location, to
update a particular area of the display.  In C this is fairly easy on a
Windows 95 machine.  Is it possible in Ada?
Thanks very much.
JM

Yes, it's very possible.  Perhaps the easiest way id to use the capabilities
of
the ANSI.SYS console device driver -- available on DOS and Win9X  (i.e., not
on NT)

The diners program in the gnat examples directory contains a screen package
to
do just that.

It provides for sounding the bell, clearing the screen, and positioning the
cursor at a specified row and column.

Thanks David,
That's perfect for what I need at this point.  I appreciate your time.

If you are thinking in terms of conio, you might want to take a look
at the nt_console package on my homepage.

Jerry,
Thanks!  That's an excellent package.  Easy to use, small, and it works.  On
Windows PC's, "working" seems to be a feature rather than a requirement,
much too often.  Your package works well.
