Once created, fields in an environment can be:

Inserted into added text or a text block. For example, inserting a name into a
message (the name is the Field Value).

Used to generate a chart.

Used to load a graphics file.

Used to perform calculations, such as totaling a column of figures. The
result can then be placed into another field.

Each environment has its own Field List, and there is no interaction between fields in
different environments.
