When using the original crc's (from crc.lst), the following files will show up as different: 2363322425 BAD addbfcrc.asm 4250916189 BAD brik.h 3534177949 BAD brik.c 2588064855 BAD brik.1 I have no idea why addbfcrc.asm and brik.1 show as different, since I made no changes to them. Possibly there were transmission errors via Usenet. I did make minor changes to brik.h (to add an #ifdef AMIGA case) and to brik.c (to make it accept names with embedded whitespace). The change to brik.c is "unofficial", but necessary to make it useful on the Amiga, since there are lots of such names. The brik.c change is enclosed in a "#if 0" sequence, so you can get the original version back if you need to. I received mail from Rahul that excluding whitespace is actually a feature. Since the lines are free format, you can manually edit the lists, and in particular, add comments after each filename. He indicated that a future version would possibly have support for embedded whitespace in names. This version of brik was used to produce CRC lists for disks 001-231 in my library, without any problems other than the initial one with embedded whitespace. The Amiga port was very painless. A very nice job Rahul! -Fred
