Do you mean a particular case for the the uname/uvalue names, or the case comparison
expression (and the like)? It's almost purely a matter of style, but I prefer the latter, e.g.

string = 'ThIsCaSe' ; case irrelevant...whatever looks nice :o)

CASE STRUPCASE(string) OF
'THISCASE':....
'THATCASE':....
ELSE:...
ENDCASE

I guess one could argue it's self-documenting and localises any confusion over the
convention chosen, but, eh <shrug>.

Anyway...

cheers,
