Yvon Masse - response re. Inclination/Declination

[Tony Moss]

The letter and program listing from Yvon Masse enabling the calculation of
Declination and Inclination of a plane in QBasic makes me wish there was
something similar written in OPL for the Psion 3C palmtop.  As a very new
owner of this little wonder I'm not yet familiar enough to attempt anything
like this for myself and wonder if anyone out there has already done so?
