...and the generic issue here is that system() calls the system shell,
and if that doesn't know of a "read" command, you're up the proverbial
roof without a paddle.

If you really insist of unix() functionality, you need a Unix-like
subsystem. You could start by installing bash.exe and do things like
system("bash -c read stuff") but you'll soon realize that you also
need all of the programs that are traditionally available on Unix.
