Dear SCO Customer,

Support Level Supplement (SLS) ptf4056a, the SCO UnixWare 2.1.3 lpc Supplement,
addresses a problem where running "lpc clean all" causes core to dump.

Note that this SLS only applies to systems with the "bsdcompat" package 
installed. It will not install if the bsdcompat package is not present.

Software Notes and Recommendations
----------------------------------

SLS ptf4056a should only be installed on:

        SCO UnixWare Application Server Release 2.1.3
        SCO UnixWare Personal Edition Release 2.1.3

If your system is running any libraries or commands that are contained 
in this SLS, then these programs will continue to run with the old 
versions of these libraries or commands until the the system is rebooted.

Note that when all necessary patches have been installed, it is
recommended that you reboot the system at the earliest opportunity.
This will ensure that no programs continue to run with the old
