[APBeta] ASTORB.cache?

[RPEHLM]

Hi gang,

Been trying to test some of the ASTORB scripting stuff.  This is what 
I'm using:

dim mpo as APMinorPlanetObject
mpo = ASTORBObject(1)

The 'mpo' assignment generates the folloing message:

"ASTORB.cache missing.  Please access 
File->Import->Comet/Minor-Planet/Supernova Data...and select the 
ASTORB.DAT option in order to create the cache."


It's not terribly clear which option I need in the 
File->Import->Comet/Minor-Planet/Supernova Data dialogue box.  After 
trying a few things clicking on the ftp link to download the ASTORB.DAT 
(third option down) seems most likely to me.  I've downloaded the file 
and saved it.  What do I do with it now?  Or have I got this all wrong 
to start with?

Regards
Robin
