if you have downloaded the starter code for pa5 and tried to assemble it before now, you have probably already found the following typo in line 49:

  ASCII_Q_COMPLEMENT  FILL  xFFAF ; two's complement of ASCII code 
for 'q'

the FILL should have a dot (.FILL)

also, the comment should say that xFFAF is the "two's complement of ASCII code for 'Q'.

these things have been corrected in the starter code. if you downloaded the starter code before 1:25pm today (11/23), then please either make these corrections to your copy of the code or re-download the code. thanks.
