Personally, I'm used to the with . convention that Visual Basic uses, but I like D's way, too. D's scope rules are already well-defined and they work. But keep these suggestions coming, D still has some weak spots and different perspectives can shed light on them. > > James McComb -- Justin http://jcc_7.tripod.com/d/ |
