That's an interesting one... it's trying to read a resource from eikon.rsc, which apparently is implicitly opened by OPL programs. (the nil index is due to our impl of ReadRsc not expecting someone to call it without ever having called LoadRsc).

The resource in question appears to be the text "Busy" so I guess this application is using it as a way to leverage existing locallisations.

Nice find!
