    I have an application that likes to take input from the keyboard one character
    at a time without waiting for a carriage return...

    I realize that I could probably accomplish this
    in the UNIX environment using the appropriate ioctl, but unfortunately my
    program was developed in the Aegis environment and I'm not quite ready
    to change it to UNIX (at least not until SR10 hits the streets.)

You would really like to do this in a device-independent manner, so that
your program doesn't have to find out what kind of a tty it has.  The only
supported way I know of to do this is with ioctl().

You don't have to "change it to Unix" to take advantage of ioctl().
Just make the ioctl call, passing in the ios stream id as the file
descriptor.

There isn't really an internal distinction between "aegis" programs and
"unix" programs.  (Well, except for case distinctions in file names).
I often mix "aegis" system calls with "unix" system calls within the
same program.

If your program is written in pascal, you may find it easiest to write a
little one-line C program to call ioctl(), and bind it in with your program.
