Re the no context: originally the code had been part of the previous node but it didn't seem to flow well so I seperated the code into it's own node - but yeah I can guess that if you saw that through Newest Nodes it might be a bit confusing.

As for the '$' being missing from arg2 - again possibly slightly confusing but it was just some testing text, to make sure that the parser would pass through arguments and so it was never intended to be a variable just some text to be displayed (obviously in the long run, this would be a variable).

For anyone who's interested in the history of the node, I was trying to come up with a command parser and had been having problems with a particular module from CPAN so the node in question had some code that I'd put together.
