Here POINTER is not "C" like pointer but it is a Byte Variable Declared whose address is 0x23. Or in other words for ease of programming, the byte at 0x23 is aliased as "POINTER".
yeah thanks..anyway, i figured out how to do what i wanted to do.
The PIC has an FSR register that acts as a pointer. Simply load the FSR with the address and access the address via the INDF register once the FSR is pointing to the right address.
