Code:
macro push arg {
       push arg
    if defined PUSH_COUNTER
             PUSH_COUNTER=PUSH_COUNTER+1
 end if
}

macro pop arg {
        pop arg
     if defined PUSH_COUNTER
             PUSH_COUNTER=PUSH_COUNTER-1
 end if
}

macro proc name, [arg] {
common
     if used name | defined INCLUDE_ALL_PROCS
    PROC_NAME equ name
  PARAM_COUNTER equ 0
 LOCAL_COUNTER equ 0
 PUSH_COUNTER=0
 
 if ~ arg eq
forward
      PARAM_COUNTER equ PARAM_COUNTER+1
   arg equ esp+(PARAM_COUNTER+LOCAL_NUM+PUSH_COUNTER)*4
common
      name#% = PARAM_COUNTER
      else
        name#% = 0
  end if
name:
}

macro begin {
     LOCAL_NUM=LOCAL_COUNTER
     if LOCAL_NUM>0
           sub esp, (LOCAL_NUM*4)
      end if
}

macro return {
 if PUSH_COUNTER<>0
            display 'WARNING: push/pop miscount',13,10
    end if

  if LOCAL_NUM>0
           add esp, (LOCAL_NUM)*4
      end if
      PARAM_NUM=PARAM_COUNTER
     ret (PARAM_NUM*4)
}

macro endp {
        if PUSH_COUNTER<>0
            display 'WARNING: push/pop miscount',13,10
    end if
      end if
}

macro ldd name {
       name equ esp+(LOCAL_COUNTER+PUSH_COUNTER)*4
 LOCAL_COUNTER equ LOCAL_COUNTER+1
}

macro lrd name, dwords {
    name equ esp+(LOCAL_COUNTER+PUSH_COUNTER)*4
 LOCAL_COUNTER equ LOCAL_COUNTER+dwords
}

macro stdcall proc, [arg] {
common
  PARAM_COUNTER = 0
   
    if ~ arg eq
reverse
      push arg
    PARAM_COUNTER = PARAM_COUNTER+1
common
   end if
      
    if proc#% <> PARAM_COUNTER
            display 'WARNING: Param miscount',13,10
       end if

  call proc
}

    


Usage:

Code:
stdcall name, 10, 100

proc name, par1, par2
ldd .Local1 ; local dword
begin
   code
   return ; U can also have multiple return points
endp
    


Features:
U can freely use ebp and still have named locals, even pushs/pops won't break your code
Warns if param miscount
Warns if push/pop miscount
Include procs only if used or INCLUDE_ALL_PROCS is defined

Think that was it.. Comments appreciated.
