Hey Tony!

 TL> Well, having the CRC32 implemented would make my script more
 TL> universal.

From what I've read thus far I seriously doubt there is such a thing as
'universal' when it comes to crc32.  However I did find at least one workable
solution (c source) that I slightly modified so that the internal printf only
outputs the crc32 8 character hex (0-9,A-F) checksum.  At the moment it is
only used by my fidonet account as I am sure that is the only place it might
ever get used and that is debatable.  However not having a common file(s) we
can test this idea with is the current holdup.  Anyhow it is around 5
milliseconds faster then the bash printf of cksum and the output is 32 bit
hex.  Your milage will vary.

 TL> I'd br hsppy to use the Perl option, if I could find it for
 TL> Raspian.

Do you currently use Raspian for fidonet?  The c source, if it turns out to be
compatible with the accepted method, would probably be a better option.

 TL> we have to work with the TIC specs here.

Says who?  ;-)

Life is good,
Maurice
