1st and 2nd Edition

# a helping function
# mbmcount.py
from struct import unpack
def readL(f, pos=None):
if pos is not None:
return unpack('L', f.read(4))[0]
# the real counting function
def mbm_count(mbm_file):
f = open(mbm_file, 'rb')
mbm_type = readL(f)
if mbm_type == 0x10000041: # mbm on ROM (Z:)
return readL(f)
elif mbm_type == 0x10000037L: # mbm on file (normal)
return readL(f, readL(f, 16)) # read at trailer
else: # what type is it?
return None

Put it in library and try this :

from mbmcount import *
# result = 503L

MIF files are used instead ! TODO : MIF files ...
