[antlr-interest] ANTLR 3.1.2: Simplest action

[Udo Weik]

Hello again Bart,

> `$text` is just a shorthand notation for `$XYZ.text` where `XYZ` is the rule you're currently in.

$INTEGER.text doesn't work ("rule INTEGER has no defined parameters"), but your $text does.
That's what I don't understand ;(.


Many thanks and greetings
Udo
