The Text Objects: 4 Text Object Chunks

Each text object contains several instance fields that may reference outside chunks. Most non-large text objects will reference the following chunks:

A text chunk containing the string of text for that object.
A lines/fields chunk containing internal information about the length and position of lines and tab fields.
A character attributes chunk, containing either a single VisTextCharAttr structure or (for multiple character attributes) a list of VisTextCharAttr structures.
A paragraph attributes chunk, containing either a single VisTextParaAttr structure or (for multiple paragraph attributes) a list of VisTextParaAttr structures.
For multiple character attributes, a chunk of character attribute runs, referencing the list of VisTextCharAttr structures above.
For multiple paragraph attributes, a chunk of paragraph attribute runs, referencing the list of VisTextParaAttr structures above.

The Text Object Library provides many other features, but these are the most often-used and difficult to master. You should have a complete grasp of these mechanisms before using either VisText or GenText. To make their use easier, both objects use these features in essentially the same manner.
