Syntax Grammar
A section of a Shape Script can be quite complex, containing a number of commands and parameters. The table below provides a breakdown of the Shape Script structure, illustrating how commands and parameters are constructed. The first entry is the top-level declaration, and subsequent entries show the composition of successively more detailed components.
