I see. If n is not fixed, the -display- directive to input numbers
would need to be supplemented by input of how many numbers you intend
to give, which probably rules it out.

I don't see why your program should not allow -input- in the middle,
but I've not tried that, or at least recently. Seems easiest to input
some numbers, then run the program.
