Instead of

iorlw   30h     ; or with 0x30

you should write the following:

Version A.

call    nibble
...
nibble: addwf   pcl
        retw    '0123456789ABCDEF'
....

Version B.
        addlw   246
        skpnc
        addlw   7
        addlw   58
....
now you have it!
(all numbers are decimal unless noted otherwise!)
