Re: Making HCELL With -?

Confused. What computer are you programming? Host's cell size and
target's aren't necessarily the same, nor do they have anything to do with
each other. In what circumstance do you care at all about the host's cell
size? I don't understand why you're making any HOST definitions here at
all. Depending on how you're using this, you may need only INTERPRETER,
possibly TARGET as well, but probably not HOST. That's only causing
trouble. One rarely needs to make HOST definitions in SwiftX.

Cheers,
Elizabeth
