 version 4.4.9, 2022-03-15, for Unix-Linux.
 homepage: https://k1.spdns.de/zasm/
 git repo: https://github.com/Megatokio/zasm

syntax:
 zasm [options] [-i] inputfile [[-l] listfile|dir] [[-o] outfile|dir]
 zasm [--version|--help]

 default output dir = source dir
 default list dir = output dir

examples:
 zasm speccirom.asm
 zasm -uwy emuf_rom.asm rom_v2.0.1.rom

options:
 -u --opcodes include object code in list file
 -w --labels append label listing to list file
 -y --cycles include cpu clock cycles in list file
 -b --bin write output to binary file (default)
 -x --hex write output in intel hex format
 -s --s19 write output in motorola s-record format
 -z --clean clear intermediate files, e.g. compiled c files
 -e --compare compare own output to existing output file
 -T --test run self test (requires test directory with test sources)
 -g --cgi prevent access to files outside the source dir
 --maxerrors=NN set maximum for reported errors (default=30, max=999)
 --date=DATETIME for reproducible __date__ and __time__
 --target=ram default to target 'ram' => cpu addresses in hex files
 -o0 don't write output file
 -l0 don't write list file
 --8080 target Intel 8080 (default if --asm8080)
 --z80 target Zilog Z80 (default except if --asm8080)
 --z180 target Zilog Z180 / Hitachi HD64180
 --asm8080 use 8080 assembler syntax
 --convert8080 convert 8080 assembler source to Z80
 -v[0,1,2] verbosity of messages to stderr (0=off, 1=default, 2=more)
 --ixcbr2 enable illegal instructions like 'set b,(ix+d),r'
 --ixcbxh enable illegal instructions like 'set b,xh'
 --dotnames allow label names starting with a dot '.'
 --reqcolon require colon ':' after program label definitions
 => label definitions and instructions may start in any column
 --casefold label names are case insensitive (implied if --asm8080)
 --flatops no operator precedence: evaluate strictly from left to right
 -c [path/to/]cc declare or set path to c compiler (search in $PATH)
 -t path/to/dir set path to temp dir for c compiler (default: output dir)
 -I path/to/dir set path to c system header dir (default: compiler default)
 -L path/to/dir set path to standard library dir (default: none)
