I can't think of the exact syntax at the minute but something like;

if $# => 4 then for i = 1 to ($# - 4) echo "arg number $i is $expr($i)" next fi

$ echo $* 1 2 3 4 $ \

...

while [ "$1" != '' ] ; do echo $1 shift done

1 2 3 4 $

...

Note that (a) the args are gone as you shift them out, so a real script would need to save $1 into a named variable before each shift if it wants the value later, and (b), '' is a legitimate and possible argument on a shell command line so it might be better to check $# for the count remaining.
