[edit] Note not understood

I did not understand this note box very well. Can some one please clear it up for me?

Note
The two 'Comparison' operators are slightly different from the rest. Rather than returning only 1 or 0, these operators return -1 if the left argument is greater than the right argument, 0 if they are equal, and 1 if the right argument is greater than the left argument.
Is that clearer now? I added that the note applies to the operators <=> and cmp. -Mairi 01:09, 10 Jan 2005 (UTC)
Yes, it is clearer now. Thank you, --Zoohouse 01:57, 10 Jan 2005 (UTC)

[edit] global versus local variables

maybe it's my setup, but i have trouble executing the code in the examples (even the Try It examples). it turns out i have to add "my" before variables - should this be part of the tutorial?
