starting a file from another directory with a script

[Michael Havens]

i ACTUALLY THINK i UNDERSTOOD THAT!

I hope Brian doesn't kick me out for all the post title changing I did. But
hey.... if the topic changes shouldn't you change the post title too? Too
make it easier to search for information! That is the main reason I posted
that..... too add to the pool of knowledge that is PLUG. I know it is
simple but hey there are sure too be other newbies that come here and are
too shy to ask anything. Whereas I talk to much!
