$! Along with a list of changed parameters
$! If the system has been up 14 days or more, it will save feedback information
$! And use it, otherwise it will use previously saved feedback information.

      Extending
          SYS$SYSROOT:[SYSEXE]PAGEFILE.SYS
      by 200000 blocks required 11 seconds.  This suggests that
      high-water marking is currently enabled for this volume.  AUTOGEN
      will not extend the file further at this time.
      If your security environment allows you to temporarily disable
      high-water marking, the suggested commands are:
      $ SET VOLUME/NOHIGH SYS$SYSTEM
      $ MCR SYSGEN CREATE SYS$SYSROOT:[SYSEXE]PAGEFILE.SYS /SIZE = 25165800
      $ SET VOLUME/HIGH SYS$SYSTEM
      The system must then be rebooted in order to use the extended file size.
