I posted to comp.sources.misc by accident.  This is a repost.

On our system running SysVr2.2, 40223 is 8093 (1F9D hex).  Use "od -x"
on a compressed file to see if your first word is different.

We changed data to file.  We also found a space in front of the '-'
was picked up leading to "compressed file - 16 bits" instead of
"compressed file- 16 bits".

Great idea!  Thanks Steve.
