Section: Introduction
|
|
----------------------------------------------------------------------
|
|
|
|
ACME is a crossassembler for the 65xx range of processors. It knows
|
|
about the standard 6502, the 65c02 and the 65816. It also supports
|
|
the undocumented ("illegal") opcodes of the 6510 processor (a 6502-
|
|
variant that is used in the Commodore C=64).
|
|
|
|
This text and the other files in the same directory only describe the
|
|
basic functions independent of the platform used. There should be
|
|
another help file in this archive that outlines the features specific
|
|
to your platform.
|
|
|
|
The files in the docs directory and what they contain:
|
|
|
|
65816.txt Stuff specific to the 65816 processor
|
|
AddrModes.txt How to choose non-standard addressing modes
|
|
AllPOs.txt Lists ACME's pseudo opcodes. Use as a reference.
|

|
IMPORTANT: If you upgrade from ACME 0.05 or earlier, don't forget to
|
|
read the file "Upgrade.txt" - release 0.07 and all later ones are
|
|
slightly incompatible to 0.05 and earlier.
|
|
|
|
If you want to start using ACME right away, read the file
|
|
"QuickRef.txt", it contains the main help text.

Section: What it can and does
|
|
----------------------------------------------------------------------
|
|
|
|
ACME is a crossassembler.
|
|
ACME can produce code for the 6502, 6510, 65c02 and 65816 processors.
|
|
It does this *fast*.
|
|
It can produce at most 64 KBytes of code.
|
|
You can use global labels, local labels and anonymous labels.
|
|
It is fast.
|
|
You can use global and local macros.
|
|
You can use conditional assembly.
|
|
You can use looping assembly (There are two ways to do this; a very
|
|
simple and a very flexible one).
|
|
You can include other source files.
|
|
You can include binary files (either whole or parts) directly into the
|
|
output.
|
|
You can use offset assembly (code that is designed to run at a
|
|
different address).
|
|
It is fast.
|
|
ACME's maths parser uses operator priorities, so 1+2*3 will correctly
|
|
give 7 (unlike some other free assemblers that give 9 instead).
|
|
ACME's maths parser has no problems concerning parentheses and
|
|
indirect addressing modes.
|
|
ACME's maths parser knows a shit load of different operations.
|
|
ACME supports both integer and floating point maths operations.
|
|
You can dump the global symbols into a file.
|
|
ACME supports a library of commonly used macros and symbols.
|
|
It always takes as many passes as are needed.
|
|
ACME exists on several platforms, meaning you can easily exchange your
|
|
sources with other people (preferring other OSes).
|
|
ACME can convert its strings to PetSCII and screen code (Okay, this is
|
|
C64-specific).
|
|
ACME has a rudimentary type checking system to catch errors like
|
|
missing '#' characters.
|
|
Did I mention that it is fast?
|
|
|
|
|
|
----------------------------------------------------------------------
|
|
Section: What it can't and doesn't
|
|
----------------------------------------------------------------------
|
|
|
|
ACME cannot transfer data to a C64 or another computer.
|
|
ACME does not produce ".o65"-format linkable object files.
|
|
ACME cannot produce more than 64 KB (would be useful for the 65816).
|
|
ACME cannot disassemble or relocate given code files.
|
|
|
|
|

|
Section: Platform independence
|
|
----------------------------------------------------------------------
|
|
|
|
ACME was initially developed under RISC OS. Currently there are
|
|
platform-specific versions available for AmigaOS, DOS, Linux, Windows
|
|
and RISC OS. The Linux sources should be ready to compile on most
|
|
other UNIX-like systems as well. In the future there will hopefully
|
|
also be a version that runs on the C64/128.
|
|
Though the source code does not exactly look like it *g*, ACME was
|
|
written with portability in mind: Some of its limitations were
|
|
included on purpose, just to allow a C64/128 version. To successfully
|
|
assemble multi-file source codes from other platforms, the file names
|
|
have to be altered as little as possible. Please name all your files
|
|
that may be distributed in a sensible way, for example by limiting
|
|
their file names to 8+3 format. I really hate this stupid will-it-
|
|
ever-die DOS convention, but using it is the only way to ensure
|
|
portability of files.
|
|
|
|
Please use ".a" as the file name extension of ACME source code files.
|
|
|
|
All file names used inside source code files have to be given in UNIX
|
|
style, ACME will convert them to the current host platform style if
|
|
needed.
|
|
|
|
There should be no problems concerning newline characters, ACME was
|
|
designed to cope with CR, LF and CRLF.
|
|
|
|
A minor problem is the different character tables used on different
|
|
systems. As all predefined ACME keywords only use 7-bit ASCII, the
|
|
assembler will work on any system that uses a superset of this
|
|
character table: UTF-8, ANSI, ISO 8859, etc.
|
|
Symbol names can contain top-bit-set characters - these may look
|
|
strange if the sources are edited on a different platform, but ACME
|
|
will still work.
|
|
|
|
If you want to port ACME to another platform, please inform me so that
|
|
I can add your version to the ones already present on the ACME
|
|
homepage. As the sources are released under the GNU General Public
|
|
License, you are not forced to do this; but it would help to make ACME
|
|
available to other users.
|
|
The same goes for any changes or enhancements to the sources: Please
|
|
send me a copy so that the changes can be incorporated into the next
|
|
"official" release on the ACME home page.
