Is there an easy way to do a clear screen for the dos prompt?
like I have a bunch of data that I have put pauses in. It would be very
helpful if I could clear the screen after every pause. thanks,

Ah, hey dude, whats happenin!

If you have gnat, then use, argh.. I forget... Gnat.OS?

use Gnat.OS

    ...
    Gnat.OS.System("cls");

Help me out here vets, I forget the exact Annex...

If you have ANSI.SYS loaded, the code is ESC[2J

There is a small annex called "screen" that acts like
an ANSI terminal emulator and even works with Win2k,
which Win2k has more or less disables ANSI.SYS if
you use CMD.EXE, old COMMAND.COM still has
it but there are problems using it.

    I hate M$! When they screwed up ANSI.SYS that
was the final straw. Now I can't even have a colorized
DOS-Box prompt thanks to those idiots. With the kind
of work I do, I need super automatic batch-mode, not
click "OK" ten thousand times in a row every ten seconds.

( And I'm sure as sh!t not going to buy "Visual Studio" when
I already have gnat / gtkAda working! )

Cheers!

ANSI was a terminal driver code that was used by a lot of
old BBS and terminal software. If you had ANSI.SYS loaded
or used and ANSI terminal then you could use escape codes
to control the screen. I will use ^[ to represent ESC, which
is octal code \033, for example ^[[ is \033[[

Clear screen: ^[[2J
Clear to end of line: ^[[K
Save cursor position: ^[[s
Go to saved location: ^[[u
Jump to screen 3:30: ^[[3:30H
Turn subsequent text bright blue: ^[[1;34m
Set text to gray: ^[[0m

Take a look at this link:

http://enterprise.aacc.cc.md.us/~rhs/ansi.html

It explains the codes. From c, if you did:

    printf( "\033[1;34mThis is blue text\033[0m!\n")

You would indeed have blue text assuming that you had an ansi driver working.

As an adendum, here is a relevant portion of my Linux
profile which gives me a nice colorized prompt. Add
it to your .bash_profile or .bashrc

Keep in mind that wherever you see ESC, with the vi
editor you should press CTRL-V ESC to embed an
actual escape character into the sequence

PS1='\[ESC[1;30m\]<\[ESC[35m\]\#\[ESC[30m\]>(\[ESC[36m\]\h\[ESC[30m\])[\[ESC[34m\]`pwd`\[ESC[30m\]]\[ESC[32m\]

$\[ESC[0m\] '


A b/w version of your prompt will be:

<13>(thunder)[/home/doug]
$

the 13 will be purple, the thunder will be bright cyan, the /home/doug will be blue,
the $ will be green, and everything  else will be bright black. Any text you type will be grey.

Regards,
- Doug

Well, that is one way to get the legal right to use the Win32 bindings. They
were translated from Microsoft's .h files, so you have to have those .h files
legitimately in order to legally use Gnat's Win32 bindings.

The following is exerpted from the footer of Win32.ads:

I solved the problem by purchasing a student version of VC++6 that came with NT
(back when I was still a student). Its fairly cheap that way, and that gave me a
legal OS for the new machine I'd just built too.

Funky. I wonder if they got permission to distribute derivative works of
Microsoft's copyrighted files.
