Hi Murray,

I spotted your little mistake, but I understood what you meant. ...
:-)

ML>  display ('     Press ENTER to stop beeping') REPLY (X);

This approach is buffered, but it does at least flush the output
buffer before soliciting input. However, it waits until return is hit
before returning control to the program.

I expect that FidoDelay has elapsed and you have seen my earlier post
about declaring the STDIN: to be unbuffered. You might need to be
careful with output buffering to get the prompt displayed before input
is solicited. You can declare an unbuffered output file and use the
WRITE statement to write to the STDOUT: device, if necessary.

I use the .CV2 include files instead of .CPY. They aren't bug-free,
but they are better than the .CPY files.
