用mpasm编译汇编代码出现错误

你好，我是学习汇编程序的。我正在编写一个我的医生的代码。这是一个：我正在使用MPASM 5.72，但是我编译时有下一个错误：你知道发生了什么吗？为什么他能编译它而我不能？谢谢

    Hello, I am learning assembler. I am trying to compile a code that a doctor of my faculty made. Is this one:
List p=16f877A
include p16f877a.inc
contador EQU 20H

CONTADOR EQU 21H
contador1 EQU 22H
contador2 EQU 23H
ORG0

goto inicio

ORG 0X04 ; atendiendo la interrupcion
goto interrupcion



org 10h

inicio

bsf STATUS,RP0 ; cambiamos al banco 1
Clrf TRISB ; configuramos el puerto b como salida

movlw b'00010000'

movfw contador2

movwf SSPBUF
movwf contador2
;loop
;btfss PIR1,3
;goto loop

retfie ;regreso de la subrutina de interrupcion

END

I am using mpasm 5.72, but I have the next error when I compile:

Error[150] C:USERSDELFINDESKTOPUNIVERSIDADSENSORESASSEMBLER_BASICSSPI_MASTER.XSPI_MASTER.ASM 13 : Labels must be defined in a code or data section when making an object file
Error[151] C:USERSDELFINDESKTOPUNIVERSIDADSENSORESASSEMBLER_BASICSSPI_MASTER.XSPI_MASTER.ASM 15 : Operand contains unresolvable labels or is too complex
Error[152] C:USERSDELFINDESKTOPUNIVERSIDADSENSORESASSEMBLER_BASICSSPI_MASTER.XSPI_MASTER.ASM 15 : Executable code and data must be defined in an appropriate section

Do you know what's going on? Why is he able to compile it and I can't? Thanks
