Hello 
I have problem with inline assembler in DJGPP.
I write this procedure in Borland C++ and I don`t how can I rewrite it
to DJGPP. Please help me.

This procedure draw point in any VESA mode.
void drawxy(unsigned x, unsigned y, unsigned char Col) 
{
  asm { mov ax,0a000h
        mov es,ax
        mov ax,y                
        mov cx,scanlength
        mul cx
        add ax,x
        adc dx,0               
        push dx
        push ax
        mov ax,dx
        xor dx,dx
        mov cx,granul
        mul cx
        cmp al,bank         
        je dale 
        mov bank,al
        mov dx,ax
        mov bx,0
        mov ax,4f05h          
        int 10h
      }
        dale:
  asm { pop ax
        pop dx
        mov di,ax
        mov al,Col
        mov es:[di],al         
      }
}
