Bill--

    IBM C Set++ has the same  non-ANSI I/O functions as all
other C compilers I am familiar with.  However, C Set++ is a little more
ANSI-compliant than many other compilers.  In accordance with the
standard, non-ANSI library functions have an underscore as the leading
symbol in the function name.

    _kbhit() returns a nonzero value if there is anything waiting in the
session's logical type-ahead buffer; it returns a zero if the buffer is
empty.  _getch() returns the first character (waiting until one appears
if necessary) without echoing that character to the screen.  (_getch()
will not read Ctrl-Brk.)  For example: if (_kbhit()) ch = _getch();

    See _kbhit() and _getch() in the C Set++ manual: "C Library
Reference" for further details.

    Hope this helps.
