Customer Set-up of Brackets Instances

The bracket set-up facility allows a customer to define a bracket standard of his own. In doing that some parameters of the brackets are given specified values, for example, toe heights, toe lengths, whereas other parameters are supposed to be evaluated or given by the user when the bracket is used.

This paragraph specifies in detail a facility by which a customer may define default values for some bracket parameters other than those that can be defined in the normal bracket set-up file. Examples of such parameters are those defining the size and thickness of a bracket. A set of bracket parameters for a certain bracket type is said to form an instance of the bracket type.

Bracket instance definitions are created by writing definition data in an ordinary text file in a special language based on The Interpretative Language (TIL). The format and the handling of the bracket instance definition file are described in detail below.
