Bob:
I really think you're going to want to get all of the developer's manuals
even if you do get Aztec. The only one that I'd call truly dispensible would
then be the Lattice manual, although even that manual contains some useful
technical information on how the Amiga loads and executes data and code
segments, etc.
The Aztec version currently in beta test comes only with a doc release..the
extensive documentation that Manx typically provides (over 200 pages for their
Mac and IBM compilers) is still being finalized for the Amiga version so I
can't comment on it yet.
