Gary:

Read the section of the datasheet that describes the FSR and INDF
registers; this is exactly what they're for.

The following bit of code copies the contents of Read_Buffer into
Store_Byte_X, where Store_Byte_X = Store_Byte_0 + the contents of
SM_Counter.

    MOVLW   Store_Byte_0    ;W = address of the start of the
                            ;    Store_Byte array.
    ADDWF   SM_Counter,W    ;W = address of the SM_Counter'th
                            ;    element of the array.
    MOVWF   FSR             ;FSR points to that address.

    MOVF    Read_Buffer,W   ;Grab the data to be stored.
    MOVWF   INDF            ;Store it in the register to which
                            ;the FSR is pointing.

If you put a RETURN at the end of the above code, it's equivalent to
your "Store_Data" routine.
