uni-SPF normally creates a new file when the SAVE command is issued.
If this file is created sucessfully, the previously saved file is
removed, and the new file is renamed to the previous name. uni-SPF
then issues 'chown' and 'chgrp' commands to change ownership to
the previous values. However, many varieties of UNIX do not allow
these commands for non-root users. In this case the saved file will
retain the userid and group of the current user.
To prevent this from happening, set the SPFTEMP environment variable
to NOTEMP before entering uni-SPF. This causes uni-SPF to overwrite
the original file when a SAVE is issued, so that the original owner
is retained. Note that if you do this, and the SAVE encounters a
file system full condition, the file being edited may be damaged
