By default, postpone adds code to the end of the file. Is it possible to postpone to the end of the specified section, and not the end of file?

like:

postpone '.code' {
...
}

Postpone doesn't know about sections.

An option is to make a named macro.
Code:
;...
section 'code' ...

macro after_code {
 ;...
}

 mov eax,0x1234
;...

after_code
;...

Yes, but there is a problem... how to find or put label to the end of the .code section automatically...

Code:
; header
macro end_of_section {} ; start end_of_section
postpone { end_of_section } ; last end_of_section
macro section args& { end_of_section ; previous end_of_section
section args
macro end_of_section \{ \}} ; new end_of_section

; main code
section '.text' readable executable
macro end_of_section { end_of_section ; recursive call
    invoke ExitProcess, 0 }
entry $
section '.rsrc' data readable resource from 'rsrc.res'
