I do
Code:
 macro inline chP {
       ;call chP
       repeat chP#_gE-chP#_gB
         load ttt byte from chP+%-1
         db ttt
   end repeat
       }

proc Pproc1 pu:dword
     rR1 EQU edx
     mov eax,[pu]
Pproc1_gB:   mov rR1,12
            imul rR1,2
Pproc1_gE:
     ret
endp 

In code:

mov eax,Pproc1
inline Pproc1

    


IDA pro get me this code. But why ?!
Code:
push    ebp
mov     ebp, esp
mov     eax, [ebp+8]
mov     edx, 0E42EE80Ch
    

I expected this:
Code:
            mov edx,12
            imul edx,2
    


If i write:
Code:
proc Pproc1 
     rR1 EQU edx     
Pproc1_gB:   mov rR1,12
            imul rR1,2
Pproc1_gE:
     ret
endp 
    


i get this:
mov edx,12
imul edx,2

I presume you want to load some code and make a duplicate?

If so then probably your load is not correct. Maybe try::
Code:
load ttt byte from chP#_gB+%-1
