With this release the 1.69 development line is finally ended. Any new development will proceed in 1.71 line, which will be available in parallel to the stable 1.70 version on the download page.

However I am not planning to start any new development soon. If I still have some spare time for fasm, I would like to finish the Understanding fasm article first.

Regarding comments in WHATSNEW.TXT

[+] Extended the syntax of "rept" directive to allow numerical expressions
to be calculated by preprocessor in its arguments.

is it possible to do something resembling this:

Code:

rept 8 c
{
    d = c+7
    xor r#d,r#d ; clear registers r8..r15
}

or should the code look like this instead:

Code:

rept 8 d:c+7
{
    xor r#d,r#d ; clear registers r8..r15
}

Simply:

Code:

rept 8 d:8 { xor r#d,r#d }

There is a very similar example in the manual.

Or perhaps you wanted an example of some looping requiring inner calculations, like skipping every second register? As this is more complex and in this case you actually need to use the new abilities of "rept" (for the above one the old "rept" was enough):

Code:

rept 4 c { rept 1 d:6+c*2 \{ xor r\#d,r\#d \} }

I just posted about this on FreeDOS' News section, though it's hard to sum up all the changes. Anyways, thanks again for your efforts.

BTW, it is also mirrored on SourceForge: http://sourceforge.net/projects/fasm/files/
I keep uploading the milestone releases there.

Would you like if I edited the announcement and added that URL too?

It's just that FreeDOS (barely) likes to have backups on iBiblio, esp. for stuff in the Software List, though (IMNSHO) it's not been well-maintained over the years and is a bit disorganized and incomplete.

Actually, the FreeDOS website (and project) are more or less hosted on SourceForge itself. See http://freedos.sourceforge.net/ , it's the same thing. (I personally don't mind backing up things already backed up elsewhere, esp. if they are important and useful. Besides, it ain't a big package anyways, it's not like I'm mirroring all of Ubuntu!!)

@Tomasz: I think I've got the answer. The example I gave (that you simplified to the example given in FASM.pdf) was not what I intend to do, but now I know how to approach my problem and that I can nest repts and use ever expanding complexities in those nested repts. Thanks!

There is also an added paragraph in section 2.3.7, which treats the special processing of symbolic variables in the parameters of "rept".

I had to re-upload the packages with a minor correction today. This would not be very important, however it changed the checksums of files - so if you have checksum stored somewhere, please update it.

It's been one million years since I last posted here, yet I kept using FASM to develop CPCE (now housed in http://cngsoft.no-ip.org/cpce/ and partially on hold because it will be fully rewritten for its 2.0 release), so I'd like to congratulate Mr. Grysztar for his always amazing work.

I'm afraid, however, that I've run into something that is either a bug or a consequence of the new features of 1.70. CPCE can be compiled into 16-bit DOS or 32-bit DPMI or Win32 binaries thanks to the usage of conditions (" if OS = 16 ... else ... end if") and definitions ("xdx equ dx" in the 16-bit binary and "edx" in the 32-bit binaries).

So far the method had worked flawlessly, but when I upgraded FASM from 1.69.42 to 1.70 lines like "mov w[xdx+1],ax" and "lea xdi,[xdx+xax-1]" were no longer accepted. Editing them by hand ("mov w[edx+1],ax") makes them work again, at the cost of depriving aliases of their strength.

Yes, it's a bug, thank you for the report.
Please try the freshly uploaded 1.70.01.

I see this "problem" too, though you can (for whatever reason) manually decode it with gzip or p7zip and then it unpacks okay (though weird in latter case).

The internal filesize is incorrectly reported or handled somehow. I'm not sure what happened, and I don't know what tool(s) he used to make the archive.

> flat assembler 1.70

Thanks Smile

1.70.02 is out:

Code:

version 1.70.02 (May 22, 2012)

[-] Corrected the optimization of segment prefixes when the extended syntax
    of some string instructions ("cmps", "lods", "movs" and "outs") is
    used in long mode. Now it is consistent with optimizations done with
    all the other instructions.

I can't find any bugs in the compiler core, just the IDE bugs are still in: http://board.flatassembler.net/topic.php?t=12553
