stdcall for dos via fasmg, is there any error in the code

Code:

Dear pals,i need 8086 codes. Thanks to the two below replies,i can use the stdcall well.
But is there any error in the codes ?

include '8086.inc'
include 'format/mz.inc'
macro stdcall proc,args&
        iterate argargs
                indx 1+%%-%
                mov bx,arg
                push bx
        end iterate
        call proc
end macro
entry code:start        ; program entry point
stack 100h      ; stack size
        segment code
start:
        push cs
        pop ds
        call main
        MOV AH,4CH
        INT 21H
main:
        push bp
        mov bp,sp
        sub sp,2
        ;
        mov bx,[-2+bp]
        mov byte[bx],10
        mov byte[bx+1],'1'
        mov byte[bx+2],'2'
        mov byte[bx+3],10
        mov byte[bx+4],'$'
        stdcall ok,9,[-2+bp]
        add sp,4
        ;
        mov sp,bp
        pop bp
        ret
ok:
        push bp
        mov bp,sp
        mov bx,[bp+6]
        mov byte[bx+2],'h'
        mov dx,bx
        mov ah,9
        int 21h
        ;
        mov dx,[bp+4]
        add dx,30h
        mov ah,2
        int 21h
        ;
        mov sp,bp
        pop bp
        ret

Are you sure you want only 8086 instructions? 'pushd' is not an 8086 instruction. Neither is 'push imm'. Perhaps you want to select a more capable CPU? You need 80386 at least to get pushd, and/or 80186 to get push imm.

Judging from the rest of code I suspect that 16-bit PUSH is needed here. Just replace "pushd" with "push".

PS. You also need to pop the right number of bytes off stack with RET.
