[Jprogramming] pattern matching in J

[bob therriault]

No problem Richard,

The quote I used was actually from Jon on his blog post, so I imagine he is already aware. ;)

If you wish to pursue the topic of language comparison between WL and J, it would probably be best to move over to the Chat forum <chat at jsoftware.com>   :)

Cheers, bob
