	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.
