Keyboard manipulation

Keyboard manipulation

[Eric poirier]

Hello !!!

I'm pretty new to ADA and to this Newsgroup. I have a quite easy
question: I know that is possible to get a character with the
Ada.Text_io.Get_Immediate command, that take the carcater without the
'return' . Okay ! Now, I'd like to know how to get the arrays caracters
(left, right, up, down) of the keyboard...
It takes... I don't know what ...

I  also know that I can use the Ada.Text_io.Put ( ASCII.XXX ) to put on
the screen, I now need to know how to compare with the character I've
got with the Get_Immediate  before ...

Thanks

Eric Poirier,

That depends on the platform and OS you are using. You may be able to
reverse-engineer it for your system by writing a little program to
output the results of a Get_Immediate. But don't expect those results to
be valid for another OS or hardware platform.

Many OS's have a high-level way to get at your special keyboard keys,
but those will be OS calls, not Ada calls.

Is something wrong with "="?

Which platform, OS ? On PC there are pairs ASCII.NUL & 'H' etc. for
special keys (according to the OS)... To test it you can
make a loop that displays the ASCII code of Ada.Text_io.Get_Immediate
via character'pos(...). It could tell things...
