ok, i forgot to close the file, but you forgot to exit the interpreter!
:)  one thing i was trying to do was to get the home environment var
and use it.  so i wanted to do something like this:

    (HOME) getenv {
	(HOME) getenv \home exch def
	\home + (/i_could_have_deleted_all_your_files) (w) files \out exch def
    } {
	(/i_could_have_deleted_all_your_files) (w) files \out exch def
    } ifelse

obviously this fails since + doesn't combine strings.  how do you combine
two strings to make one?  something like

    (fu) (bar) concat
