     1.  Release 5.1 of TOPS-20 and 4.2 of GALAXY  must  be  installed
         before attempting to install IBMCOM on the KL.

     2.  The regular distribution tapes for TOPS-20 5.1 contain LPTSPL
         and CDRIVE built with the correct versions of D60JSY.

     3.  In IBMCOM, since communication is expensive, it is  sometimes
         preferred  to  not  have SPRINT delete a recently transmitted
         card  deck.   To  help  with  this  situation  the  following
         unsupported patch is provided:

         In order to assure that SPRINT does not delete files that  do
         not  appear to have a correct $JOB card replace the following
         lines in SPRINT:

                PUSHJ   P,PROCER                ; Do ABORT processing
         EOF.1: PUSHJ   P,RELREQ                ; Send "release" to QUASAR
                MOVE    S1,L.IFN                ; Release the input file

         with

                PUSHJ   P,PROCER                ; Do ABORT processing
                PUSHJ   P,RELREQ                ; Send "release" to QUASAR
                MOVE    S1,L.IFN                ; Release the input file
                PJRST   F%REL                   ; and do not delete!
         EOF.1: PUSHJ   P,RELREQ                ; Send "release" to QUASAR
                MOVE    S1,L.IFN                ; Release the input file

         Please note:  with this patch, all decks without  $JOB  cards
         will  be  retained.  The system administrator should be aware
         that this could  allow  a  malicious  user  to  fill  up  the
         PS:<SPOOL> area with trash files.
                                                                Page 2


     4.  A new system logical name, D60:, must be defined.  The IBMCOM
         spoolers  use  this logical name for looking up signon files,
         signoff files, and for creating  input  files.   Placing  the
         following in the system CONFIG file is a convenient method:

              DEFINE D60:  PS:<DN60>

         This makes the default for D60:  the same directory  used  in
         release  4.0.   D60:   can,  of  course,  be  defined  as any
         directory  on  any  structure  normally  mounted,   if   more
         convenient  for  operations.   But  if  the structure used is
         non-PS:, the job should do a mount of  the  structure  before
         starting the spooler.
