Dear vadana:
Thanks your excellent macro file. But I can't understand the nested macro define. Can you give some description about it ?
Thank you.

Code:

macro string_data {}

macro STRING name,str
{
  macro string_data
   m_
          string_data
         name db str,0
       _m
}

m_ fix {
_m fix }

In STRING macro it will define new version of string_data macro and insert old version of string_data at the beginning of it.

Code:

macro string_data {}

macro STRING name,str
{
   macro string_data ; defines string_data macro
   m_
      string_data    ; inserts old version here
      name db str,0
   _m
}

m_ fix {
_m fix }

STRING foo, 'foo'
;after that string_data is:
;foo db 'foo',0

STRING bar, 'bar'
;after that string_data is:
;foo db 'foo',0
;bar db 'bar',0

Dear aaro:
Thanks your reply. But I found that the complier maybe present a serious bug about the nested macro define. Please see the belowing demo code:

Code:

macro string_data {}

macro STRING name,str
{
   macro string_data ; defines string_data macro
   m_
      string_data    ; inserts old version here
      name db str,0
   _m
}

m_ fix {
_m fix }

     org     100h                    ; code starts at offset 100h
        use16                           ; use 16-bit code
   STRING  foo,'foo'
 STRING  bar,'bar'
         
display_text = 9
        mov     ah,display_text
     mov     dx,hello
    int     21h

     int     20h

hello db 'Hello world!',24h

The complier result is wonderful. It shows on the belowing: (The file size is 22 bytes)

Code:

0B56:0100  B4 09 BA 09 01 CD 21 CD-20 48 65 6C 6C 6F 20 77   ......!. Hello w
0B56:0110  6F 72 6C 64 21 24 99 C3-2E C7 06 55 91 00 00 2E   orld!$.....U....

The complier result file don't define the foo and boo variable .
Why?

You have to use that "string_data" macro somewhere. Currently you only define the macros.

Hi,Privalov:
Thanks you helpping. I have added the "string_data" macro on the code.
But I have found two results:

1. The "string_data" macro on the front of "STRING", the complier result file doesn't present the foo and bar variable.

Code:

string_data
STRING    foo,'foo'
 STRING  bar,'bar'

2. The "string_data" macro after of "STRING", the result file is OK.

Code:

STRING       foo,'foo'
 STRING  bar,'bar'
 string_data

I have maze the behaviour the nested macro define. Can you explain more information about it?
Thank you.

Hi,Vadana:
The .for macro present a bug and I have fixed it . Please see the belowing code:

Code:

macro .for var,cond,val1,oper,val2,_step,stepval
{
local ..continue,..break,..endfor,..beginfor
  __BEGINFOR equ ..beginfor
   __CONTINUE equ ..continue
   __BREAK equ ..break
 __ENDFOR equ ..endfor
       __VARIABLE equ var
  __OPERATOR equ oper
 __STEPVAL equ stepval
       mov     var,val1
    __CONTINUE:
     __BEGINFOR:
     cmp     var,val2
    if oper eq to
               jge     __ENDFOR
    else
                jle     __ENDFOR
    end if
}

It should be the belowing code:

Code:

macro     .for    var,val1,oper,val2,_step,stepval
{
local     ..continue,..break,..endfor,..beginfor
      __BEGINFOR      equ     ..beginfor
  __CONTINUE      equ     ..continue
  __BREAK         equ     ..break
     __ENDFOR        equ     ..endfor
    __VARIABLE      equ     var
 __OPERATOR      equ     oper
        __STEPVAL       equ     stepval
     mov     var,val1
    __CONTINUE:
     __BEGINFOR:
     cmp     var,val2
    if oper eq add
              jge     __ENDFOR
    else
                jle     __ENDFOR
    end if
}

Thank your macro file.

Hello all.
You dont need call macros init_string or init_data.
You must init .data section, and strings or other init automaticly, becouse I create new macros .data:
macro .data
{
section '.data' data readable writeable
string_data
dword_data
word_data
char_data
struct_data
array_data
}
The .data section must be placed after .code section
For macros work:

.for eax equal 15 to 30 step 2
...
.endfor

Good luck!!!
.:: VDN ::.
Very Happy
