	We are working with the Athena Text widget in V11R3
and would like information on the fields for the source and sink.
The manual for the Athena widgets does not say much about them.
Specifically we would like information on each of the functions in the
source - Purpose, parameters and Errors that are returned. For example,
what is the difference between the Disk and String sources besides
the fact that the Disk source uses a temporary file for storage? When
do we use which?

	We need to change the edit mode and commands depending on the
position of the cursor in the text. The application has a representation
of what should be displayed and what is editable. This seems to imply that
we must provide our own source that will change the modes as the cursor
moves or selections are made. Does anyone have any ideas? We have looked
at the source code for xedit, xman, and the Disk and String sources. However,
this has not left us with a clear idea of how to implement our interface.

Thanks in advance for any help.
