The problem is to do with the fact that output to a console or terminal
is generally line-buffered - ie : output is put into a buffer a line at
a time, and isn't written to the screen until a newline is sent.

You can force output to be written to the screen from the buffer by
putting "fflush(stdout);" after your printf statement.

Might I suggest that the ILUG list isn't *really* the place for basic C
programming questions like this, and that a decent book on C programming
in the Unix environment might be a good investment?
