Description
-----------
zmac is a rather good Z80 macro cross-assembler which hardly anyone
seems to know about, but which I've used for about four or five years
now for various things.
I'd taken to, whenever I uploaded any of my Z80 sources, including a
diff to get zmac minimally working (being a relatively old program, it
made some assumptions which were a little odd in a modern context) and
a pointer to where the shar archives could be found. (FWIW, that's
comp.sources.unix volume 9.) But eventually, I decided it'd be a Good
Thing if I got a more reasonable zmac package together, especially
since I couldn't ever remember seeing a Z80 cross-assembler on
sunsite. Honestly, why bother wasting space on junk like the kernel
and gcc when you could be using it for *useful* stuff like Z80
assemblers? :-)
So I made the code ANSI C and got it through gcc's `-Wall', fixed a
couple of obscure bugs I'd found in it, wrote a man page, and added
the option of only accepting 8080-compatible instructions so you can
write programs in Z80 which will also run on the 8080 and 8085 (see
the man page for details), and a couple of other minor features. And
that's essentially what's here.
The documentation is in the file zmac.doc (derived from the Un*x
man page in the file zmac.1 ).
Installation on Un*x
--------------------
You'll need an ANSI C compiler. gcc is fine - so should most other
compilers be, these days. (You'll also need bison or yacc, if you
want to build from scratch, but that shouldn't be a problem.)
Check/edit the Makefile first. (It should be fine, though.) Then do
`make', then (as root) `make install'. This installs the man page
as well as the executable.
Installation on BeOS
--------------------
You'll need an ANSI C compiler. gcc is fine.
You should be able to use the Makefile provided, otherwise just
do whatever you need to do to compile zmac.c, mio.c and getoptn.c
together.
Then put the executable in /boot/home/config/bin/ or
/boot/beos/bin/ .
Installation on DOS
-------------------
You'll need an ANSI C compiler.
You may be able to use the Makefile provided, if you're using
djgpp, otherwise just do whatever you need to do to compile
zmac.c, mio.c and getoptn.c together; in both cases make sure
the preprocessor token MSDOS is defined.
Then put the executable somewhere in your PATH.
Installation on RISC OS
-----------------------
You'll need an ANSI C compiler. Acorn C/C++ is fine, and
so should gcc and lcc be.
You may be able to use the Makefile provided, otherwise just
do whatever you need to do to compile zmac.c, mio.c and getoptn.c
together; in both cases make sure the preprocessor token __riscos
or __riscos__ is defined (this is the case for Acorn C/C++,
gcc and lcc).
Then put the executable somewhere in your Run$Path.
[Also see the file RISCOS.]
Installation on other OSes
--------------------------
You'll need an ANSI C compiler.
You'll probably need to add filename-handling support for
your OS. This involves adding appropriate definitions
of OS_DIR_SEP and OS_EXT_SEP and adding appropriate code
to decanonicalise (). In those cases where directories in
pathnames are syntactically distinct to leafnames (e.g. VMS)
changes will also be needed in suffix () and suffix_if_none ().
You may be able to use the Makefile provided, otherwise just
do whatever you need to do to compile zmac.c, mio.c and getoptn.c
together.
Then put the executable somewhere appropriate, and feed your
changes back to <mrison@hotmail.com> so they can become part
of the source source!
History
-------
Bruce Norskog wrote zmac in 1978, "modeled after the ... macro
cross-assembler for the Intel 8080 by Ken Borgendale."
John Providenza made some changes and bugfixes in the early 80s.
Colin Kelley did much the same in the mid-80s.
And of course, I've just messed about with it in the late 90s,
together with Mark RISON, Chris Smith, Matthew Phillips
and Tim Mann. :-)
I assigned the first version I hacked on the version number 1.0 just
for the sake of argument (previous versions didn't have a version
number). A version number of about 4.0 or 5.0 would probably be a
better reflection of what the code's been through over the years...
