For those reading this thread who don't want to take the time to  
follow up on Logan Copaldo's ( (excellent) suggestion, here is some  
code contemplate. Parentheses matter.

Regards, Morton

#! /usr/bin/ruby -w

require 'curses'
include Curses

init_screen
begin
    i = 60
    # Works
    addstr((i / 60).to_s)
    addstr("\n")
    # Works
    addstr((i / 60).to_s) if (i % 60 == 0)
    addstr("\nPress any key to proceed: ")
    refresh
    getch
ensure
    close_screen
end
