In a UI-View overlay file (*.pos located in the OVERLAYS folder) a line
starting with an asterisk is a comment line.

The file contains a list of items with their location and an optional status
text line... e.g.

LadyMinto>Lady Minto Hospital - Ganges, BC

The name in both lines must be identical with a maximum of 9 characters.
It doesn't have to be padded to 9 characters like an object. It's a maximum
of 9 characters... e.g.

EOC>Emergency Operations Centre

It doesn't go out on RF, but having a standard would be useful for other authors.
Compatibility with what goes out on RF is of more importance, but it would
certainly be a convenience if users of various APRS clients could share POS files.
