We have SysVr2.2 and the 40223 needed to be changed to 8093 (1F9D hex).
Use "od -x" on a compressed file to see if your first word is different.

We also found a space in front of the '-' would be included in the
output leading to "compressed data - 16 bits" instead of "compressed
data- 16 bits".

Much thanks for the idea.
