        pretty sure I tried something like this about a week ago.
        maybe last monday.  it may have segv'd.  but YES in cp_text.c
        is ::


        if (p)
        {
           fprintf (stdout, "%s", p);
           L[i++] = p;
        }

        here "p" is  the string or stringgs *within* /tmp/file/text.N.txt;
        I planned on passing "L[]" to what you have above: "first text",
        "second text".  

        in my example text.1.txt files I have (e.g.) "i am bringing this
        laptop to the group so I can be more easily understood."

        many thanks indeed.  I'm' going to save your mail and get a 
        hardcopy.  tthen join the directories, &c.
