<<I tried using Get_Immediate with GNAT (3.05) on Solaris and I didn't get
the results I wanted.

What I got:

My program reads each key, and I don't have to type Enter, but it also
echoes each key. When I type a key that sends an escape sequence, like
an arrow key, all of the codes in the sequence are echoed, e.g. ^[[A,
before my program gets the first character of the sequence. Also, some
keys, like Ctrl-C did not get read by my program.

What I want:

I want to read without any echoing and be able to get all of the codes
the keyboard can generate.

Can you tell me how to get these results?>>


You probably need to give more detail, what machine are you on? (remember
Solaris does not imply Sparc!)

Also, you need to say what interface you are using, since keyboard input
is often filtered in various ways by the environment. For example, the
situation using X directly on a Sun work station may be radically diferent
from the situation of using a terminal emulator remotely (in the latter
case, the "codes" from the keyboard may be dependent on the terminal
emulator).

If the problem is echoing, then you may well want to use appropriate
OS dependent routines that are around in your environment to do exactly
what you want, using pragma Interface.

But in any case, update to a more recent version, 3.05 is pretty ancient
at this stage!
