Looks like it might be this scheme: https://en.wikipedia.org/wiki/DEC_Radix-50 36-bit word for a 6-char filename, but there was also a 16-bit variant. I do like that filename scheme you describe, though it would tend to produce names that would suit virulent diseases. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
