Thank you Michael for the suggestion.
I was hoping there may be a programmatic alternative (I should have
mentioned) to defining in the grammar each and every keyword alternative.
I now see from some archived posts (ANTLR 2) suggestions of over-riding
testLiterals method and programmatically checking the 'current' token
against a hash.
Does anybody have an example of how to provide this functionality in ANTLR
3 (other than defining each alternative)?
The author of this archived post hints at a solution:

Unfortunately the link he provides is dead:

Thank you,
Shaun
