Thank you for the tip. This helped a lot.

Tomasz, can you please give some tips for writing more optimal calminstructions and macros in general (if its optimization can have any overal impact)
For example,
- is it better to use long expres ...

Ah, I see. I tried wrapping all in "namespace", obviously without success. Thanks a lot!

Looks like no, as

calminstruction inst
local sym

arrange sym, '1'
asmcmd =display sym

local sym
asmcmd =display sym
end calminstruction

just displays two '1's

Maybe a dumb question, but I do not completely understand what happens inside when I define the same local symbol many times.

calminstruction inst
local sym, sym
end calminstruction

Worked like a charm! Thanks!

I created a macro to encrypt a block of data with RC4.

macro rc4 block_start, count {
local K, S, i, j, Si, Sj, Ki, x, y

Thanks for the workaround, revolution. Source doesn't compile with the latest fasm, but I found 1.73.04 build somewhere on the internet and it worked fine.

What is EFI boot in your understanding?

Yeah, I used his macros for some time, but was not completely satisfied with what features they provide. Mine are independent. However, I use slightly modified utf8 to wide string conversion macro fro ...

Hi guys! In the beginning of the new 2018 year I'd like to share with you my project I've been recently working on: ebc.asm

It is a set of macroinstructions, structures, and constants defining full ...

Indeed, it's so obvious. I just overthought it too much. Thanks

How can I optimize the following line (for fasmg):

if (num > 0 & num < 65536) | (num < 32768 & num >= -32768)

P.S. not knowing num bit length (num can be 32 ...

Thanks a lot!
