Pete's description of the subshell problem for Linux is correct.
Actually, when I first tried system("cd ...", 2) on DOS I was
somewhat surprised that it worked, since a subshell is
created on DOS too. I guess the current directory is a
global property on DOS.
I'll add a library routine in Linux, as well as DOS and
Windows, that will switch to a new current directory.
It will have the advantage of returning an error code
to indicate success or failure.
