Code:

macro .multisection [entry_file] {
        common
        macro proc [param] \{ 
                end if
                if cuRRent='code'
        \}      
        macro endp \{
                end if
                if cuRRent='code'
        \}
        macro .data \{ 
                end if
                if cuRRent='data'
        \}
        macro .idata \{ 
                end if
                if cuRRent='idata'
        \}
        macro .code \{
                end if
                if cuRRent='code'
        \}
        macro .comment \{
                end if
                if cuRRent='comment'
        \}
        macro .dataonce name
        \{
                end if
                if name=0 &cuRRent='data'
                        name=1
        \} 
        section '.idata' import data readable writeable 
        cuRRent='idata'
        forward
        if cuRRent='idata'
                include entry_file
        end if
        common
        section '.data' data readable writeable 
        cuRRent='data'
        forward
        if cuRRent='data'
                include entry_file
        end if
        common
        cuRRent='code'
        purge proc
        purge endp
        macro proc [param] \{ 
                \common
                end if
                proc param
                if cuRRent='code'
        \}      
        macro endp \{
                end if
                endp
                if cuRRent='code'
        \}
        section '.text' code readable executable
        entry $
        sub rsp,8
        forward
        if cuRRent='code'
                include entry_file
        end if
}

FEATURES:
1. Linker. It will combine all your sections in all project files at same time.
2. Proc. You can use multisections inside procedures.
3. Unlimited sections any time you need it.
4. Easy to add some more kind of sections like .rsrc
5. Short names like masm .code .data (up to you actually)
6. No need of .end
7. Comment whole block by .comment
8. Macros inserts Data just once by .dataonce

Do not use fix inside linked files. Do not declare sections inside if operators.
To enjoy it put(include) the macro to Header(Main file) then link your project files by:

Code:

.multisection '<your project file 1>','<your project file 2>','<your project file n...>'

Seems like idea is to use some sort of different names, but I think we can use files to store all subsections together.

Good macro somthing like this:

macro .dll [arg] {
section '.idata' import data readable writeable
library arg,`arg#'.DLL',\

import_#arg

}

In code:
.dll kernel32,user32,gdi32

This is why I like masm -- simple sections, sticked together by compilation. I mean .code .data...Any macro can make parts for sections. What's wrong with fasm?

I don't know man, the last time I tried, MASM's '.data' macro still unable to align to 32-byte boundaries. Horrible macro for dealing with YMM data. Had to move down to raw "dseg segment". I hope it is already fixed by now.

I did it

Code:

macro .multisection entry_file {        
        macro .data \{ 
                end if 
                if current='data'
        \}
        macro .idata \{ 
                end if 
                if current='idata'
        \}
        macro .code \{
                end if
                if current='code'
        \}
        current='idata'
        section '.idata' import data readable writeable
        if current='idata'
                include entry_file
        end if
        current='data'
        section '.data' data readable writeable 
        if current='data'
                include entry_file
        end if
        current='code'
        section '.text' code readable executable
        entry $
        sub rsp,8
        if current='code'
                include entry_file
        end if
}

Put this macro on header/Main file or include it to there.
Write your program on some separate file then put it there by
.multisection '<your program>'

Upd: Use it carefully with "fix" where you need it. Declare it before or after multisection.

New feature:
.comment

        macro .comment

Easiest way to comment whole block of code when you need it. Enjoy Wink

New feature:
.dataonce <unique name>

Code:

macro   .dataonce name
        {
        end if
        if name=0 &cuRRent='data'
                name=1
        }

Example:

Code:

dataSomeMacro = 0                     ;declare unique name
macro SomeMacro [arg]
        .dataonce dataSomeMacro          ;once again
                Param1 db ?
                Param2 db ?
        .code                                    ;finish job by declaring next section.
                mov [Param1],1
                lea arg,[Param2]
        }

SomeMacro rsi
...
SomeMacro rdi
...
SomeMacro rax

Data block will be added to data section just once. No matter how many times you use your macro. Don't try to use multisection blocks inside 'if -end if' constructions, just in main macro body. But you can use 'if - end if' inside that sections as normally do.
Have a look to my new macro .function. That one can be used with 'if - and if' without problems.

I tried to hide that ugly unique names for all, but not success. Have to be used with names for a while Smile
