The "Get_Immediate" procedure in the Ada 95 Ada.Text_IO is designed to provide
this, though it is still implementation-dependent whether on any
given operating system, this capability is/can be supported.

For Ada 83, or Ada 95 systems where Get_Immediate does not provide
the desired functionality, you should be able to use pragma Interface 
(Ada 83) or pragma Import (Ada 95) to connect up to the appropriate 
underlying system call.  Alternatively, your compiler may already
come with a means of accessing this underlying operating system
capability.

If you could specify the compiler and the hardware/OS platform, we
could probably provide more help.  You should also consult whatever
literature is available on the compiler you are using, especially if
it is an Ada 83 compiler.  For Ada 95, Ada.Text_IO.Get_Immediate should
do the trick, if the underlying O/S supports it.
