Dear SCO Customer,

Support Level Supplement (SLS) ptf7651a, the UnixWare 7.0.0 to 7.1.1 
nroff/troff Y2K Number Register Supplement, addresses the following problems:

  - The predefined number register "yr" is documented as being the last 
    two digits of the year, whereas it was actually the year 1900.  Thus, 
    the year 2000's value is shown as 100 rather than the expected 0.  
          
  - The mm macro package's predefined date string "DT" was returning 
    something similar to "January 1, 1900" instead of the expected 
    "January 1, 2000".  Similar problems with the me macro package 
    ("td" string) and ms macro package ("DY" string) also occurred.

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

SLS ptf7651a should only be installed on:

        UnixWare 7 Release 7.0.0, 7.0.1, 7.1.0, 7.1.1


NOTE:  This supplement has been superseded by
the UnixWare 7.1.1 Maintenance Pack for UnixWare 7.1.1 platforms
only.  The UnixWare 7.1.1 Maintenance Pack is available from:

ftp://ftp.caldera.com/pub/unixware7/uw711pk


Note that if you want the yr register to print as two digits, you may 
have to set its format using:

             .af yr 01

SLS ptf7651a only applies to systems with the bsdcompat package 
installed.  It will not install if the bsdcompat package is not 
present.

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
libraries or commands.
