    C) achs0300.20s1  - the script file to execute
    D) achs0300.20s2  - the file containing the scripts
    


III.  REQUIREMENTS

    A) CHS V 3.0
    B) IBM RS6000 running AIX and the ksh shell.  Scripts will not run
       on Microsoft DOS, Window 95/98/2000 or NT boxes.



IV.  INSTALLATION INSTRUCTIONS

    A) Disable menu option ACHSMENU.

    B) Backup all CHS routines using %RS.
        1) D ^%RS
        2) select HFS.
        3) enter save file name such as 'ACHS_P20.20000915',
           where 20000915 is the date the snapshot is created.
        4) enter a comment such as 'Pre patch 20 snapshot'.
        5) select routines 'ACHS*' and 'AZZ*'.


    C) Perform KIDS install of file achs0300.20k.

    D) Enable menu option ACHSMENU.

    E) This step is for area office installs only.  It must be performed by
       a user with root or super user privileges.  It is only necessary if
       the area office has not updated their scripts since before patch 17.
        1) cd /usr/spool/uucppublic
        2) chmod ug+rwx achs0300.20s1
        3) ./achs0300.20s1
{Note - due to the differences in the way your AIX systems
 may be set up, the dot slash may not be needed.  If you
 type it as is and it does nothing, try just    achs0300.20s1 }


    F) In the event of an install failure, restore the snap shot file
       created in step IV.B.
        1) D ^%RR
        2) enter snap shot file name from step IV.B.3.
        3) restore all routines.
        4) To back out the script install at area offices only, a user
           with root or super user privileges will do the following.
           == indicates a comment, do not type that, but do what it
           says.  Otherwise, type the line exactly as it appears,
           followed by a carriage return.
            a) crontab -e
            b) == Use the cursor control key to get to the first entry
