hi Wink

Is it possible to concatenate two "equ" ?
Code:
A1 equ aaa
B1 equ bbb

C1 equ ??? ; <--- C1 = A1 + B1 (Is it possible to do that ?)

maybe:
Code:
C1 equ A1B1; C1 equ aaabbb

Code:
if

A1 equ /      ;or /*

then

does not work.
    

it's a pity, this would have been useful .

ouadji,

It's only backtick that don't work. Symbol C1 is defined as /bbb. Try
Code:
match c, C1 { irps s, c \{ display \`s \} }    
to display it's value.

yes, it works (display), but
in fact, I would like to do this:
Code:
A1 equ "
B1 equ /*
match concat, A1#B1#A1 ; A1#B1#A1== "/*"
{ 
  C1 equ concat 
}
mov eax,'C1'  ; == mov eax,'"/*"'
    

but I think I am asking something impossible!

sorry but my English is not good enough to explain all this,
and edfed is French.

et non ce n'est pas inutile, pas dans mon cas.
Dans mon code, celui qui permet les commentaires multi-lignes et en blocs, je fais à plusieurs endroits référence aux symboles "start-comment" et "end-comment" ... Pouvoir définir ces symboles start/end avec des EQU m'aurait permis de changer rapidement de symboles dans tout mon code. Par exemple, passer de "/* */" à "(! !)". Je peux le faire, mais il faut que je définisse la totalité des "cas" ... exemple ... pour mov eax,'"/*"' ... je peux définir par un EQU <toto equ '"/*"'> et écrire ensuite : "mov eax,toto". Ca, c'est ok. Mais il faut alors que je définisse par des "equ" tous les cas ... "'/*'", '"/*'", "'*/'",'"*/"' . Pouvoir agir avec "equ + concaténation" m'aurait permis de changer uniquement 2 equ ...
celui pour /* et celui pour */. Les autres cas seraient alors définis d'office par concaténation. voilou.

my solution
Code:
@S_ equ 2A2Fh
@E_ equ 2F2Ah

@S_qd = (@S_ shl 8) or 22000022h
@E_qd = (@E_ shl 8) or 22000022h

mov eax , @E_qd  ; mov eax,'"*/"'

if i change @E_ ... @E_ equ 2921h 
then, i have : mov eax,'"!)"'

ouadji,

Why are you need all those combinations of quotes? Half of them are invalid anyway: string literal must end with the same quote (single or double) as it was started. Wink

Backtick macro operator works in match too: match c, `A1#`B1 { C1 equ c } defines C1 as string '/*'. Moreover, simple Wink macro can be used to stringify (almost any) sequence of symbols:
Code:
COMMENT_START equ / *
COMMENT_END equ * /

struc textequ arg {
  local r
  r equ
  match v, arg \{ irps s, v \\{ match vv, r\\\#\\\`s \\\{ r equ vv \\\} \\} \}
  match v, r \{ . equ v \}
}

COMMENT_START_STRING textequ COMMENT_START
COMMENT_END_STRING textequ COMMENT_END

display COMMENT_START_STRING, 13, 10, COMMENT_END_STRING, 13, 10

SSQUOTED_COMMENT_START_STRING equ "'" shl 24 or (COMMENT_START_STRING) shl 8 or "'"
SDQUOTED_COMMENT_START_STRING equ "'" shl 24 or (COMMENT_START_STRING) shl 8 or '"'
DSQUOTED_COMMENT_START_STRING equ '"' shl 24 or (COMMENT_START_STRING) shl 8 or "'"
DDQUOTED_COMMENT_START_STRING equ '"' shl 24 or (COMMENT_START_STRING) shl 8 or '"'

mov eax, DDQUOTED_COMMENT_START_STRING    
The possibilities are endless! Wink

to make coments on fasm, we use the ;

pour ce qui est du français, evidement que l'on peu comprendre le français ecrit lorsque l'on connait l'anglais, car l'anglais est une langue qui à importé une tonne de mots de france. mais les ont mis en anglais.
donc, on peu facilement anglishiser un mot français.
par exemple:

j'aime les galettes

i love the galets

ok, it is not always true.
Smile.

de plus, le russe est inspiré du français en partie car était la langue de la cour du temps des tsars. donc, les russes n'ont pas de merites a comprendre el français.
d'ailleur, un petit suet sur le russe serait interressant sur ce forum.
par exemple, du russe orienté fasm. Smile


n'empeche, je ne comprend pas pourquoi utiliser le C design dans fasm.

fasm is made to code asm
gcc is made to code C
then, if you want to code C, use GCC, not fasm. Smile

I only need 4 combinations.
"/*" ; "*/" ; '/*' and '*/'.
this, inside my multiline-comment code.
These combinations should not be detected as a beginning or end of comment (nested or not)

Macros are an unknown world for me.
There is not much information about this in the fasm doc.
Where to find good documentation on the macros language ?
Where to find good explanations and examples ... not in fasm.pdf.

Code:
start_symbol equ /*
end_symbol equ */

struc textequ arg { 
  local r 
  r equ 
  match v, arg \{ irps s, v \\{ match vv, r\\\#\\\`s \\\{ r equ vv \\\} \\} \} 
  match v, r \{ . equ v \} 
}

@S_ textequ start_symbol
@E_ textequ end_symbol

@S_qd equ '"' shl 24 or (@S_) shl 8 or '"' 
@E_qd equ '"' shl 24 or (@E_) shl 8 or '"'
    

thank you very much baldr Razz

This solution is perfect and meets my needs exactly.
But where did you learn the macros language ?
Where to find good documentation about this?

Holy the google: http://translate.google.com/#auto|en|
The more macro the less assembler and more http://board.flatassembler.net/topic.php?t=11242&start=18(see baldr's post).

Perhaps they learned how to use macros from examples posted by someone else (mostly Tomasz). There is nothing what can be called "documentation of FASM macros", not to mention "good documentation".

You know Irish?!?
