Suspect you're usig a PIC microcontroller.
More explanation would help.

Nothing special to comment for the code except that it is setting port RA0 as ouput in line #5, port RA1 as input in line #6. Lines #4 and line #7 make no sense because status register is destination for arithmetic results, so to read and not to write into it. Lines #11 and #12 do nothing: an andoperation between register 'w' (=0xFF) and register 25 leaves register 25 as it was.
