Due to the interpretive, expression-oriented nature of the Ruby Language and implementation, each line often may contain many possible stopping points with possibly different event type. In a debugger it is sometimes desirable to continue but stop only when the position next changes. Setting 'different' to on will cause each 'step' or 'next' command to stop at a different position. Note though that the notion of different does take into account stack nesting. So in ARGV.map {|arg| arg.to_i} you get a stop before ARGV as well as one in the block. If you to ignore stopping at added nesting levels, there are two possibilities. 'set step nostack' will ignore stack nestings levels on a given line. Also you can use 'next', but that also stepping into functions on different lines to also be skipped. See also 'step', 'next' which have suffixes '+' and '-' which override this setting.
