Perhaps something like this :

;  Recevied char in rx_data, 'A'-'G', or hex '41'-'47'
;  Subtract hex '41' from rx_char and add
;  result to pcl.
;
   movlw   0x41
   subwf   rx_data, w
   addwf   pcl, f
   goto    do_A_Converstion
   goto    do_B_Converstion
   goto    do_C_Converstion
   goto    do_D_Converstion
   goto    do_E_Converstion
   goto    do_F_Converstion
   goto    do_G_Converstion
;
;  do something else...
