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?
Original fasm macros uses it once and uses .end macro -- such a silly.
Lets do something with it. Also I don't use entry, end entry etc. First .code section means that for me.

Code:

macro .data {
     section '.idata' import data readable writeable
     library kernel32,'KERNEL32.DLL',\
             user32,'USER32.DLL',\
             gdi32,'GDI32.DLL',\
             advapi32,'ADVAPI32.DLL',\
             comctl32,'COMCTL32.DLL',\
             comdlg32,'COMDLG32.DLL',\
             shell32,'SHELL32.DLL',\
             wsock32,'WSOCK32.DLL'

     import_kernel32
     import_user32
     import_gdi32
     import_advapi32
     import_comctl32
     import_comdlg32
     import_shell32
     import_wsock32

     all_api

     section '.data' data readable writeable 
}
macro .code {
  section '.text' code readable executable
  entry $
  sub rsp,8
}
macro .rsrc value { section '.rsrc' resource from value data readable }

How to remake this macros to stick side by side?
Have I use some additional include files as '.code and data.inc' and "if defined" once "store" all lines on it until next pseudo section started? Is it even possible at all?

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

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.

UPDATED RELEASE Cool

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'
        \}  
        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

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...>'

New feature:
.comment

Code:

        macro .comment
        \{
                end if
                if cuRRent='comment'
        \}

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