Including User-defined Attributes in Specifications

To include the settings of user-defined attributes in a Specification, for subsequent use by Isodraft, use the command syntax

EXTRA  :uda_name   attribute_setting

For example:

EXTRA :colour ’green’(where :colour is a uda of type text)

EXTRA :diagonal 226.87(where :diagonal is a uda of type real)

User-defined attribute settings included in this way (one per line) will be correctly output and re-input when you list the SPEC using macros.

Note:
User-defined attributes to be used in this way must have been defined in Lexicon with SPCOMs as valid components.
