The file decus-8-167.pa is the file as read, with mark parity. The file decus-8-167.pal has been modified as follows: At line 65, the PAUSE directive has been commented out. At line 218, the comma has been moved to be adjacent to the symbol being defined (ROTAT). At line 265, spaces have been moved around to make clear that addition of one is intended, not ORing with +1. At line 353, illegal octal values "08" and "09" have been replaced with "10" and "11", hopefully in line with the intent. The file decus-8-167.pal was then assembled to create the .bin and .lst files.
