I'll answer the second question.

To take a number like 1234567890, you've got two obvious (to me) choices.

One, to do a bunch of IP and MODs and division by 10s and all that stuff.

Or, do a STR-> to make it "1234567890", then a DUP SIZE to get the length
of the thing, then a loop from 1 to size to extract each digit in turn
(e.g., "1234567890" n n SUB will extract the nth character as a string),
then a OBJ-> on the returned character to change it back to a number.

If you then want to, you can REPL the number back into the string, and 
at the end of it all, do another OBJ-> to get your new number back.
