Hi all,

The J phrases book has simple uses of colon which I can't find in the NuVoc
grammar.
Could someone help explain the grammar of the following?

Verb trains:

even=: 2: * i.
odd=: 1: + 2: * i.

These seem to work without the colons anyway. What is the grammar rule and
purpose for an integer followed by a colon?

Great fun so far with J!

Thanks

Jon
