SYNOPSIS
========
**zmac** [*--help*] [*--version*] [*--dep*] [*--mras*] [*--od dir*] [*--oo sfx1,sfx2*] [*--xo sfx1,sfx2*] [*--dri*] [*--rel*] [*--rel7*] [*--nmnv*] [*--z180*] [*--fcal*] [*--doc*] [*--zmac*] [*-8bcefghijJlLmnopstz*] [*filename[.z]*]
DESCRIPTION
===========
zmac is a Z-80 macro cross-assembler. It has all the features you'd
expect. It assembles the specified input file (with a '.z' extension
if there is no pre-existing extension and the file as given doesn't
exist) and produces program output in many different formats. It also
produces a nicely-formatted listing of the machine code and cycle
counts alongside the source in a ".lst" file.
To reduce clutter and command line option usage, by default all zmac
output is put into an (auto-created) zout subdirectory. For file.z
the listing will be in zout/file.lst, the TRS-80 executable format
in zout/file.cmd and so on. For more friendly usage in make files
and integrated development environments the -o, --oo, --xo and --xd
options may be used to select specific output file formats and where
they are written.
Undocumented Z-80 instructions are supported as well as 8080 and Z-180
(aka HD64180).
zmac strives to be a powerful assembler with expressions familiar to C
programmers while providing good backward compatibility with original
assemblers such as Edtasm, MRAS and Macro-80.
This man page only documents the command-line options. The full documentation can be found here:
/usr/doc/zmac-|version|/zmac.html
OPTIONS
=======
Space-separated arguments in the ZMAC_ARGS environment variable are added to the
end of the command line.
--help Display a list of options and a terse description of what the
options do.
--version Print zmac version name.
--mras MRAS compatibility mode. Any ? in a label will be expanded to
the current module identifier as set by \*mod. Operator
precedence and results are changed.
--od dir Place output files in dir instead of the default "zout"
subdirectory. Creates dir if necessary.
--oo hex,cmd
Output only the the file types by suffix. Multiple --oo
arguments may be used. "--oo lst,cas" is equivalent to "--oo
lst --oo cas". See "Output Formats" for a list of output types
by suffix.
--xo tap,wav
Do not output the file type types listed by suffix.
--dri Enable compatibility with Digital Research (CP/M) assemblers:
Ignores dollar signs in constants and symbols. Silences a
warning when using Z80.LIB. Allows the use of '*' in first
column for comment lines. Accepts $-MACRO directives.
--nmnv Do not interpret Z-80 or 8080 mnemonics as values in
expressions.
--rel Output ".rel" (relocatable object file) format only. Exported
symbols are truncated to length 6.
--rel7 Output ".rel" (relocatable object file) format only. Exported
symbols are truncated to length 7.
--zmac zmac compatibility mode. defl labels are undefined after each
pass. Quotes and double quotes are stripped from macro
arguments before expansion. $ is ignored in identifiers
allowing foo$bar to construct identifiers in macro expansions.
Use ` (backquote) instead in normal mode. Labels starting with
"." are temporary and are reset whenever a non-temporary label
is defined (thus they may be reused). Labels starting with "_"
are local to their file thus avoid multiple definition when
brought in with include.
--z180 Use Z-180 timings and extended instructions. Undocumented Z-80
instructions will generate errors as the Z-180 (or H64810) does
not support them. Equivalent to .z180 pseudo-op.
--dep Print all files read by include, incbin and import.
--doc Print full documentation in HTML format to standard output.
-Pk=number
Set @@k to the given numeric value before assembly. Up to 10
parameters can be set from 0 though 9. -Pk is shorthand for
-Pk=-1. For example, P4=$123 effectively puts @@4 equ $123 at
the top of the first file.
-Dsymbol Define symbol to be 1 before assembly.
--fcal Always treat an indentifier in the first column as a label.
zmac uses various heuristics in the case of ambiguity when a
label does not have a colon. This option turns heuristics off.
-8 Accept 8080 mnemonics preferentially and use 8080 instruction
timings. Equivalent to .8080 pseudo-op.
-b Don't generate any machine code output at all.
-c Don't display cycle counts in the listing.
-e Omit the "error report" section in the listing.
-f List instructions not assembled due to "if" expressions being
false. (Normally these are not shown in the listing.)
-g List only the first line of equivalent hex for a source line.
-h Display a list of options and a terse description of what the
options do. (same as --help)
-i Don't list files included with include, read or import.
-I dir Add dir to the end of the include file search path.
-j Promote relative jumps and DJNZ to absolute equivalents as
needed.
-J Error if an absolute jump could be replaced with a relative
jump.
-l List to standard output.
-L Generate listing no matter what. Overrides any conflicting
options.
-m List macro expansions.
-n Omit line numbers from listing.
-o filename.cmd
Output only the named file. Multiple "-o" options can be used
to name a set of different files.
-p Use a few linefeeds for page break in listing rather than ^L.
-P Output listing for a printer with headers, multiple symbols per
column, etc.
-s Omit the symbol table from the listing.
-t Only output number of errors instead list of each one.
-z Accept Z-80 mnemonics preferentially and use Z-80 instruction
timings. Equivalent to .z80 pseudo-op.
