#Fuses

I have used the #fuses to configure the contoller, but it has no effect on code.
i.e. I have used code protect & EEprom read protect but it has no effect.
Code:

#include "16F887.h"

#fuses INTRC_IO,WDT,PUT
#fuses MCLR,PROTECT,CPD,BROWNOUT
#fuses BROWNOUT_NOSL,NOLVP
#fuses DEBUG,WRT

#ZERO_RAM
#DEVICE ICD=TRUE

The line in bold will cause the compiler to disable your PROTECT
statement.

Here is the reason. From the MPLAB ICD2 Help File:
Quote:

Q: Can I use code protection with MPLAB ICD 2?

A: No. Code protection, especially table read protection on any area in
program memory will prevent MPLAB ICD 2 from functioning. Do not use
any code protection or table read protection configuration settings when
debugging with MPLAB ICD 2. Code protection can be enabled when
programming a part for testing without MPLAB ICD 2.
