I know what's happening, but I'm not sure how
to fix it.

Windows/DOS isn't UNIX, of course. The command
"dir" is not an executable, but a built-in to the shell.
I have a vague memory in the COMMAND.COM 
days of using a string like "command /c dir" from
within a C program. I think it's called CMD.EXE
nowadays; I tried something similar a day or two ago, 
but with no luck.

Let us know what you find out.

Thanks,
Hal
