Okay. So the problem is really inside of the interpreter and
assumptions that have been made regarding what the program is going
to want to do.
I would suggest an enhancement that would allow writes to CON to
operate under the same assumptions that writes to the screen via
standard out. Perhaps you could create another file number which is
ALWAYS connected to the screen.
In my Turbo pascal programs, I had to specify that the I/O not be
buffered for the particular file I opened on the CONSOLE.
Thanks for the info. It explains what I had already suspected but
could not find documented anywhere.
