Vocabularies

You will likely have times that you will want to hide words, but access them later on. In the Rx Core, a limited form of vocabularies allows this to be accomplished. Two words are provided to create and work with named vocabularies. A simple example of a vocabulary in use is shown below.

voc: foo
foo
10 constant a
20 constant b
^
: bar foo a b ^ * . cr ;

You can open a vocabulary by calling its name. Vocabularies may be opened at any time, however only one can be open at a time. Use ^ to close the open vocabulary at any time.

TIP: If you use a . suffix on your vocabulary names, you will get a nice effect in the source, similar to dot notation in many OOP langauges.

voc: foo.
foo. : main ." main!" cr ; ^
foo. main ^

This may help improve readability if you are coming from an OOP background. Luke (docl) suggested this approach.
