Hi
What is wrong on it?

Code:

macro proc [param] { 
        common proc param }
.....
proc    DlgProc         uses rbx rsi rdi,hWnd,wMsg,wParam,lParam
.....
endp

proc DlgProc uses rbx rsi rdi,hWnd,wMsg,wParam,lParam
D:\TOOLS\Fasm\INCLUDE/MyMacros.INC [14] proc [2]:
common proc param
D:\TOOLS\Fasm\INCLUDE/macro/proc64.inc [308] proc [2]:
\{ define@proc name,<params \} }
D:\TOOLS\Fasm\INCLUDE/macro/proc64.inc [308] match [0]:
\{ define@proc name,<params \} }
D:\TOOLS\Fasm\INCLUDE/macro/proc64.inc [338] define@proc [1]:
if used name
processed: if used wMsg
error: missing end directive.

Error(s) occured.

Looks like ..... is the source of trouble.

Works fine without that simple macro. Proc itself is very intricate already.

Overclick: Post something minimal we can compile without having to guess what you have done.

Oh sorry, it happens inside an other macro only.

Code:

macro set_it {
        macro proc [param] \{ 
            common proc param \}
}
set_it

Does it make any difference?

Compiles fine for me

Code:

1 passes, 0 bytes.

The common needs to be escaped or it is processed at the wrong level.

Code:

macro set_it {
        macro proc [param] \{
            \common proc param \}
}
set_it
