Rick,
Going strictly from memory (so don't hold me to it), I think the cost of
upgrading to 4.0 from version 3.10 is $40, and is $75 if you're upgrading
from an earlier version (like the version sold under the CBM label).
Hope this helps…Bob
The current version of Lattice C is 4.01. The change seems to be mainly bug
fixes. Lattice has a patch available to change 4.0 to 4.01 available on
their BBS. The phone number's in the manual.
