Hey Tony!

 TL> I got an 8 digit decimal output from cksum

It needs to be converted to hex for comparitive purposes;

  printf "%08X\n" 89108290

which outputs 054FAF42 which differs from the DOS output - E6A6D14C.

 TL> which is either too short to be 32 bit

Unsigned 32 bit integers vary from 0 to 4294967295, which correspond to
00000000 to FFFFFFFF in hex speak.  The eight digit hex output requires
padding for integers less than 268435456.

Life is good,
Maurice
