Defining Block Variables?

alrighty I've been workin with squeak sutbly haven't really looked at any tutorials but I'm wondering how to define a block command like "#doUntil" I guess its called a variable. but I was just wondering where you define them and how you set up an area to use them or if you just add them into an existing area that has extra space.

Re: Defining Block Variables?

Blocks like 'doUntil' are called special-form blocks -- they have custom (or special) evaluation procedures. These are actually defined in ScratchProcess, not ScriptableScratchMorph
