There is a set of four Get_Immediate procedures defined in RM95 A.10.1
which get the next keystroke from either the Standard Input (usually
the keyboard) or from an open text file, and either return when the
next character is available, or set a Boolean variable indicating
whether there was a new character available. The combinations of
these options make up the four overloaded procedures.
If you do not have the Ada95 Reference Manual (RM95), its available
in Windows Help format on my FTP site in the directory
ftp://ada95.com/pub/rm95-winhelp/
>What is "GNAT" ?
GNAT is a freely-availabel compiler of the GNU family, with
implementations on a wide variety of platforms -- various flavors of
UNIX, Windows9X/NT, DOS, Macintosh, etc.
The public versions produced by Ada Core Techoligies (ACT) are
available at ftp://ftp.cs.nyu/edy/pub/gnat, while others done by
volunteers are available at various places.

This is an edition included with various textbooks, but is limited
in the size and complexity of the programs which it can produce.
There is a commercial version available without the limitations.
