 `I've modified the MicroEMACS that came with the Mark Williams C compiler to
 `read standard input (e.g., you can put it at the end of the pipe and then
 `view/edit the stuff that came out the pipe).  Is there any way to re-connect
 `the console to standard input so that a program (which itself used standard
 `input) run from within the editor via system() will operate correctly?
 `
 `In UNIX this is done by:
 `	tty = open("/dev/tty", 0);
 `	close(0);
 `	dup(tty);
 `	system("whatever");	/* "whatever" now has access to proper stdin */
 `
 `I've tried a similar technique using the ST's "con:" device in place of
 `/dev/tty but to no avail.  Can anyone offer a solution?

Fforce (0, -1) or Fforce (0, Fopen ("con:", 0));
