No - so long as you understand the concept of indirect
addressing. Only thing wrong with the FSR is there aren't
two of them -[rectified on some newer PICs].

Just pay attention to the paging bits as others have mentioned,
and use the following to load a variable address into FSR:

movlw   variable_name
movwf   FSR

Using < movlw > is the key.
