I've been searching around the message board for information on a "Get
Key" function for Fortran - the ability to have a program read input
from a keyboard without having to push enter - and I've found a few
posts that explain the difficulty of this. However, the posts I could
find were at least a decade old, some older than that.

If you don't mind using something non-standard, I know that
GFortran has an FGET extension for this. It's likely that
G95 has a similar extension.

My mistake. I just realized that FGET doesn't quite do what
you want. It just reads in stream mode, it won't get the
input for you immediately after a key press.

What I do in WATCOM FOrtran 77 (www.openwatcom.org)
is have a little "pragma" (short assembler program embedded
in the source) which looks at the keyboard strobe and gets
the keycode if there was a strobe. If it's a key I don't want,
I clear the strobe and return "no key".
But other fortrans don't have this ability. Too bad.
