This is the first 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.
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. For this first tape you should use the
TSUALL.CTL file to load updates from the TSU tape.
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 first 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. For this first TSU tape users 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
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.
A monitor patch is required for the proper functioning of
the LODxxx.CTL files and the TSUALL and TSUNEW control
files. If DUMPER complains with "?Illegal to change
specified bits" you must do the following:
wopr 1[ 641057,,100000 641057,,700000
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 monitr with MDDT.
