In some datasheets this is the initialisation example and commenting

eg 18F1x20

CLRF PORTA ; Initialize PORTA by clearing output data latches
CLRF LATA ; Alternate method to clear output data latches
MOVLW 0x7F ; Configure A/D
MOVWF ADCON1 ; for digital inputs
MOVLW 0XD0 ; Value used to initialize data direction
MOVWF TRISA ; Set RA<3:0> as outputs, RA<7:4> as inputs

Some comments have not been included in the 16F1934 code
