CHOOSE:SPELLS has an example of:
however loader indicates that it should be 'ALL' rather than ANY
Confirmed - x = ALL is the standard primitive.
FAVCLASS:x|x.y also has examples indicating 'ANY'
However, I couldnt get this to work with 'ALL' either, should it be 'HIGHESTLEVELCLASS' as used in the srd35/basics/rsrd_races__base.lst ?
Possibly worth a global search on "ANY" in the docs.
You are correct Dave. See DOCS-36. It's in the queue to get fixed.
