This is the second TOPS Software Update tape for TOPS-20  KS
V4.1 and unbundled supported products.

TSU supports updates for BASIC-PLUS-2  V2A,  COBOL-20  V12C,
DBMS  V6.1, FORTRAN-20 V11, SORT-20 V4D, and bundled TOPS-20
V4.1 components including GALAXY.

Starting with TSU tape 02 we have modified  the  TSUNEW  and
TSUALL   control   files  to  expunge  update  areas  before
attempting to load files from  the  tape.   This  action  is
taken  to  reduce  the  possibility  that  errors will occur
because a directory has too many entries.   Unless  you  are
using  TSU  for  the  first time, you should restore the new
*.CTX files from the first saveset and  rename  them  to  be
*.CTL.

If you are using TSU for the first time, you should use  the
TSUALL.CTL  file  to  load  updates  from  the TSU tape.  We
recommend that you start with the product distribution tapes
rather than the previous Autopatch areas.  There are control
files in the first saveset to assist in setting  up  product
areas.

There are many files in the Language Sources saveset of  the
TOPS-20 distribution tape which require the BLISS-36 product
in order to compile.  If you do not have BLISS-36 or do  not
want  to  maintain  these  files, you may delete these files
from your update area.  There is a file (DELBLI.CMD) on  the
first  saveset  to  accomplish  this.  You also will need to
modify the TSUNEW.CTL and TSUALL.CTL  files  to  remove  the
verification process which uses the LNGSRB.VFY file.

The TSU update process does not  rebuild  products  at  your
site.  If you need to rebuild a product then you need to use
standard building procedures.  These are documented  in  the
installation  guides  for  the specific products.  Note that
standard pre-built components,  including  the  monitor  and
EXEC, are delivered on the TSU tape.

The DBMS V6.1 interface modules have been  included  in  the
CBLSRC  area.   The  TSU  process delivers a pre-built COBOL
compiler with DBMS enabled.  The library and OTS do not have
DBMS  support.  To reintegrate updated DBMS support into the
OTS and library submit the DBMS20.CTL file as  described  in
the DBMS Installation Guide.

All files for unbundled products are encrypted  on  the  TSU
tape.   Even  though the files have a normal name, they will
not function properly until they have been  decrypted.   The
TSUALL  and  TSUNEW control files will decrypt automatically
using the new APUTIL tool.  This tool uses file lists  which
are  supplied on the TSU tape.  The manual use of APUTIL, if
needed, is described in the TSU.MEM file.  You may also  use
the DCRYPT tool which is supplied on the TSU tape to decrypt
a file.  The required KEY files were shipped on  the  latest

product  distribution  tapes  or  have been recently shipped
separately to maintenance customers of record.

The TSU tape has three major sections, as described  in  the
TSU.MEM file.  The second section, NEW, contains files which
are new for this TSU tape.  The TSU tape contains some files
in  the  NEW  section  for products which have no new edits.
This is a result of the new internal process we are using to
gather  product updates.  The files have not been previously
delivered but do represent the latest  maintained  state  of
the product.

All files in the NEW  section  also  appear  in  the  UPDATE
section.   If  you  are  using  TSU  for the first time, you
should create directories for the desired products  and  use
the LODxxx.CTL files to do initial loading from distribution
tapes.  The TSUALL.CTL file is then used  to  restore  files
from  the  UPDATE  section of the TSU tapes.  For subsequent
TSU tapes the TSUNEW.CTL file is used to restore files  from
the NEW section of the TSU tapes.  Read the TSU.MEM file for
details.

The SORT distribution is  included  as  part  of  the  COBOL
distribution.   The  SORT files are restored with the LODCBL
control file.  The LODSRT control file is only used with the
separate SORT distribution tape.

Both LODSRT and LODCBL use the  logical  BASE:   defined  as
TSU:<UPDATE>.   If  you  do  not  have  this  directory  the
definition of BASE:   must  be  changed  in  order  for  the
control files to function properly.

**IMPORTANT**

A monitor patch may be required for the  proper  functioning
of  the  LODxxx.CTL  files and the TSUALL and TSUNEW control
files.  This problem is fixed if you  are  using  a  monitor
from  any  TSU  tape.  If DUMPER complains with "?Illegal to
change specified bits" you must do the following:

@enable
$get system:monitr
$st 140
DDT
wopr 1[   641057,,100000   641057,,700000
^z
$save system:monitr

or manually restore  either  TSU:[T20SYS]2020-MONMED.EXE  or
TSU:[T20SYS]2020-MONSML.EXE  from  the  second  save-set and
rename to system:monitr.

Either way the system must then be rebooted unless you  also
apply the same patch to your running monitor with MDDT.
