This mailing list is for Scheme standardization. There is no standard
way to do what you want, so you have to look at the documentation for
the Scheme implementation you are using.
R7RS-small will have the procedure `command-line`, which returns the
command line as a list of strings. Currently, Racket, Gambit, Bigloo,
scsh, Guile, Kawa, Chibi, Ikarus/Vicare, Ypsilon, Mosh, IronScheme,
KSi support `command-line` more or less, but not very consistently.
In particular, sometimes the car of the list is argv or something
like it, but sometimes it is argv. R7RS takes the former view.

informally-specified bug-ridden slow implementation of half of Common Lisp.
