Curl macros introduction (part 1)

[glennmcgrath]

The difficulty for understanding {value} is especially obvious when using at the top level of a curl applet file. To understand this, a user must know a DefaultDocument or PlainDocument will add an object without being defined with a varirable to it's layout container (a TextFlowBox) by default , while a variable definition will be kept as a variable only and value of this variable won't be added to it's layout container implicitly. So when you want a variable to be added to a DefaultDocument or PlainDocument, eithier use {value var} at the top level of the *Document, or wrap this variable with another Graphical container like a Fill or Frame or anything else, which is then instantiated directly at the top level of *Document without being assigned to any variable.
