ANSI clear screen [MS & Borland]

[ritchie]

Hi,

I am trying to clear the screen in my program.
I am loking for something that will work on all compilers, especially
Borland & MS Visual Studio 6.
On Visual studio I used 'system("cls"); ' and this works fine but this
won't work for Borland.
On Borland I used 'clrscr() ' function and it worked ok, but not for
Visual Studio.

Is there anything that will clear the screen in both and maybe also
work on gcc?
In Borland I want to use 'easywin.exe' instead of the console window
and clear the screen.

I thought that 'system("cls"); ' would work with this?

Any ideas?

Thanks in advance,
Ritchie

That should work on both compilers given that you're making a win32 console
application.

Since you carefully read the FAQ, you are now aware that this
cannot be done in standard C. About the closest you can come is:

puts("\n\n\n\n\ n\n\n\n\n\n\n\n \n\n\n\n\n\n\n\ n\n\n\n\n");

and you may need to adjust the \n count.

After all that, don't do it. There is nothing more annoying than
gratuitious screen clearings from imbecelic programs removing data
I want to remain visible.

And that (as you know) isn't a portable technique either.

Nothing wrong with clearing the screen (by which I really mean the current
terminal window), as long as he puts the old data back afterwards. :-)

Maybe putchar('\f').. . if that doesn't work, use the compiler-provided
implementations and wrap them around #defines. (Presumably each
compiler will #define some macro identifying it. I know GCC does. If
Borland and Microsoft don't, you're probably out of luck.)

No need to put it back. I use a damp cloth and a tiny little bit of
detergent to clear the screen, and the data doesn't get rubbed off -
it stays nice and clear where it was. :)

I tried this on my teletype and now my doctor says I'll have to write
wrong-handed till the burns heal. :-(

See, these problems wouldn't arise if people didn't give offtopic
answers here. Any fule kno that your kind of router is pronounced to
rhyme with shouter, and the sort you /should/ have wiped with solvent
is pronounced to assonate with tooter. If only you yanks could learn
to spel too, we'd be laffin.

Disagree. Consider a calculator program. While using it I want
the data that was previously left on my screen.
