Dear SCO Customer,

Support Level Supplement (SLS) PTF7018A, the UnixWare 7 memsize Patch,
contains a modified memsize(1M) command. This version of the memsize command
is able to report the memory size of system dumps that are bigger than 2GB.

Previously, the memsize command couldn't report the memory size of a system 
dump bigger than 2GB. Therefore, the ldsysdump(1M) command, which uses memsize,
could not handle a system dump bigger than 2GB. 

SLS PTF7018A contains modifications to this UnixWare 7 package:

   Base System                         (base)

If you are preparing to install this package, discontinue the installation 
of PTF7018A, install this package first, and then install PTF7018A.

Note whether or not this package is affected by this SLS.  If you later 
install this package on your system, you must reinstall PTF7018A to get 
the fixes for this package.

Notes on the fixes included in this SLS can be found on the FTP server or, 
after its installation, in: 

   /var/sadm/pkg/ptf7018/install/ptf7018.txt


Software Notes and Recommendations

SLS PTF7018A should only be installed on:

The command will return "UnixWare 7" if this release is installed.

"patch uw7rs uw7rs - SCO UnixWare 7 Release Supplement."

Testing of the modified software contained in this SLS has been
conducted only to the extent necessary to confirm that it resolves
