Hi there,

DJGPP uses the unix style of buffered output (or so it seams). Bascially
this behaviour is correct, but annoying if you don't know about it. The
reasone is that stdout stream is line buffered, this means that all the
output to the screen is not sent to the stdout until a newline is entered.
In your program you can avoid this by setting a newline at the end out
your out putstring. "Hello\n". This will force the output to stdout at
once.

Hope this helps.
