Hello,
The page at the URL below describes an extensive cross macro/assembler which runs under Windows
http://www.brutaldeluxe.fr/products/crossdevtools/merlin/
Source (VS2010) is included in the archive pointed to by the download link at the bottom of the page so that you can add extra output formats yourself.
The macro assembler allows for a syntax equivalent to the Merlin suite of assemblers (by M. Glen Bredon and released for the Apple 2 and then for the C64).

HTHATS,
Benoît

A while ago I received VS2005 patches for xa. I'd be delighted to hear if they still serve for Win64 (I don't have a Windows machine of my own to test with).

I tend to prefer ca65 (from the cc65 suite). It's the most powerful one I've worked with, and is great for large multi-file projects.

It builds from source under cygwin just fine.

I've been using 64tass-1.51-883 to try and compile FIG FORTH. It pretty extensively uses the TASS .BYTE directive with an embedded string. 64tass does not like this construct one bit.



I read through the docs and it looks like you're supposed to replace it with a .TEXT directive. Which will be a bit painful with the FIG FORTH source. Am I missing anything?

If it requires a separate directive for strings versus bytes, can you put it all in a macro to not only keep in on one line, but make it easier and more readable?

What's an additional VIA among friends, anyhow?

Thanks, a macro is probably a good idea.

A new update came out today for 64Tass. It's quickly becoming a 65816 powerhouse. Version 1.51.943 has the following fixes & added features (text is from the author):

Fixes:

Wrong address on empty .fill/.align in listing
Limit function recursion
Another to early compilation stop case fixed
Proper 65816 PC wrapping
Better position reporting of invalid characters in .shift/.shiftl/.null
Include instructions without result lines in listing
And all those crash bug fixes I better don't list here

New:

65816 rep/sep tracking, added .autsiz/.mansiz
Add random() and .seed
mcedit syntax highlight added
.dpage and .databank can be "unset" now
String constant prefixes 'n', 's', 'p', 'l' added
PEI with direct page addressing
PC has type now
.rta and .addr accepts ,k now
Add empty string error message for clarity

Hi Martin,
You have the right idea about using the .text directive.
Just put the directives on different lines like so:
