PRESERVE Command
Function
The PRESERVE command changes the protection code in the owner
field of the specified file to 1. If the system default is
<055>, PRESERVE changes the code to <155>. If the system default
is <057>, PRESERVE changes the code to <157>. For information
about protection codes, see the help file PCODES.
This command runs the COMPIL program, which interprets the
command before running PIP.

The actions performed by the PRESERVE command are
meaningful only to the KJOB and LOGIN CUSPs.

TEST SFD 1 <755> dd-mmm-yy
TEST REL 1 <055> dd-mmm-yy
