I prefer using binary when doing things like this, then comment
underneath. Also, '1' looks like 'I' (input) and '0' looks like 'O'
(output)

PORTC =3D b'00111110'

eg (view in fixed font)

         movlw   b'00111111'
;                  -                output, not used
;                   -               output, not used
;                    1              input, feed reset, pull-up
;                     1             input, limit microswitch 1, pull-down
;                      1            input, limit microswitch 2, pull-down
;                       1           input, AN2, keypad
;                        1          input, AN1, feed pot
;                         1         input, AN0, rotate pot
