本人初学，遇到菜鸟问题，请教大侠

这是一个除法程序   

.title "asm test"
  .global START
  
  .sect  "init"

        Num16    .set 0x0009h
        Den16    .set 0x0003h 
        
  .text
  START: MOVU   ACC, @ Num16
        MOV   PH,  @ Den16
        RPT   #16
 ||SUBCU   ACC,@PH
        MOV   T,@AH
        SB    START, UNC

编译时总是提示：

"asmtest.asm", ERROR!   at line 6: [E0002] Invalid mnemonic specification
         Num16    .set 0x0009h

"asmtest.asm", ERROR!   at line 7: [E0002] Invalid mnemonic specification
         Den16    .set 0x0003h

"asmtest.asm", ERROR!   at EOF: [E0300] The following symbols are undefined:
3 Assembly Errors, No Assembly Warnings
  Num16
  Den16

Errors in Source - Assembler Aborted

>> Compilation failure

这么写有什么问题啊？？谢谢各位
