The "iargc" and "igetarg" solutions posted are good ones.  I have found
that some machines (notably the series 800, but that was a few years
ago) don't recognize igetarg.  By using the "guess method" I came upon
a call to "getarg" which is 
     call getarg(num,arg)
where "num" is the argument number, arg is character variable to get argument.
This works on Sun, and Apollo.  On the 800, I believe argument 1 is the
program name, on the others it is the first argument.  I use iargc on all
the machines to get the number of arguments (again, test this stuff before
using it).
