Summary: USE Keyword Instruction

Initial Comment:
Referring to documentation rev. 655.

p. 78: The documentation misses the description of the ellipsis "..."

The ellipsis ("...") can be given in place of the last variable in the USE
STRICT ARG statement and indicates that more arguments may follow.  It allows
defining a minimum amount of arguments that must be supplied or for which there
are default values defined and that may be followed optionally by any additional
arguments.

Example:

        call test "one"
        call test "one", "two"
        call test "one", "two", "three"
        call test "one",      , "three", "four", "five"
        exit

        test: procedure   /* a minimum of one argument must be supplied */
          use strict arg v1, v2="zwei", ...

          say "There are ["arg()"] argument(s); v1,v2=["v1","v2"]"
          do i=3 to arg()
             say "                       arg #" i"=["arg(i)"]"
          end
          say "--"
          return


Output:

        There are [1] argument(s); v1,v2=[one,zwei]
        --
        There are [2] argument(s); v1,v2=[one,two]
        --
        There are [3] argument(s); v1,v2=[one,two]
                               arg # 3=[three]
        --
        There are [5] argument(s); v1,v2=[one,zwei]
                               arg # 3=[three]
                               arg # 4=[four]
                               arg # 5=[five]
