1.0    INTRODUCTION


This document describes procedures for building  and  installation  of
all  supported  COBOL-74  system  configurations.  It assumes that the
installation is licensed for COBOL-74 and SORT.

The distributed compilers are prepared to support DBMS-10 and  MCS-10,
however,  they  run perfectly well without it.  The only difference is
that the DBMS-10 and MCS-10 reserved words are always active under the
version  12C standard configuration.  This was done to simplify adding
of DBMS-10 and MCS-10 to user systems, and to  simplify  and  increase
the  reliability  of  packaging  and  installation  procedures.   Most
configurations can be generated simply by reloading  portions  of  the
system.   System  installation of the distributed configuration can be
accomplished by simply  copying  a  set  of  files  according  to  the
instructions in Section 3.

Note, additional work must be done to the OTS to support  DBMS-10  and
MCS-10 This is described in the appropriate set of procedures starting
with section 4.3.

In order to obtain a configuration other than that distributed, all or
part  of  the  COBOL-74  system  must  be  rebuilt before installation
according to the appropriate set of procedures in Section 4.

Please read this guide fully before attempting to rebuild the COBOL-74
system.   Rebuilding should not be necessary unless you want to change
the feature test switch settings or have local patches to install.

If you wish to rebuild all or part of  COBOL  then  the  supplied  CTL
files can be used without modification provided that certain rules are
obeyed.  See Section 4.0 for more details.

2.0    CONTENTS OF THE DISTRIBUTION TAPE


This distribution tape is written in BACKUP INTERCHANGE format at 1600
and contains the complete COBOL-74 system.  There are eight save sets.
If any save sets are empty then you are not licensed to receive  their
contents.

The save sets are:

           1.  DOCUMENTATION
           2.  BINARY
           3.  COBOL-SOURCE
           4.  SORT-SOURCE
           5.  COBOL-BUILD
           6.  SORT-BUILD
           7.  CONVERSION
           8.  TEST


The DOCUMENTATION save set contains the following files:

          CBL12C.INS    -- this file
          COBOL.BD     -- directory of BINARY save set
          COBOL.SD     -- directory of COBOL-SOURCE save set
          SORT.SD      -- directory of SORT-SOURCE save set
          SORT.BD      -- directory of BINARY save set
          COBOL.RD     -- directory of COBOL-BUILD save set
          SORT.RD      -- directory of SORT-BUILD save set
          68274.DIR    -- directory of the CONVERSION-UTILITY save set
          COBOL.UTD    -- directory of the UETP-DIRECTORY save set
          CBL12C.BWR   -- the Beware file for COBOL-74 12C
          CBL12C.DOC   -- the Doc file for COBOL-74 12C
          SRT4D.BWR    -- the Beware file for SORT 4D
          SRT4D.DOC    -- the Doc file for SORT 4D
          NEW-ISAM.MEM -- the Doc file for ISAM
          *.HLP        -- the Help files for COBOL and SORT etc.
          68274.MEM    -- the Doc file for the conversion utility
          KEYRMS.CBL   -- the RMS example shown in the appendix I



The COBOL-SOURCE save set contains all the source  files  required  to
build  COBOL-74.   There  is no need to load these files onto the disk
unless you want to rebuild the COBOL-74 system.  The building  of  the
complete  COBOL system requires about 10,000 blocks of free disk space
and about 1 hour of CPU time on a KL-10.

The SORT-SOURCE save set contains all the  source  files  required  to
build the stand alone SORT and the COBOL SORT.

The COBOL-BUILD save sets contain the REL, UNV files, etc.   from  the
final  build.   These  files  can be used to rebuild the corresponding
compiler if only minor changes have been made (i.e.  bug fixes) rather
than a feature test switch change.
COBOL-74 FOR V12C ON TOPS-10: INSTALLATION GUIDE                Page 5


Similarly the SORT-BUILD save set contains the  REL,  UNV  files  etc.
from the final SORT build.

The CONVERSION save set contains the REL, UNV, files, etc.   from  the
build  of  the  conversion  utility (68274).  The files can be used to
rebuild the utility when bug fixes have been installed.

The TEST save set contains all files which may be used to test  COBOL.
These may be copied to UTP:.

3.0  INSTALLATION OF THE COBOL SYSTEM


This section details the procedure for installing the COBOL-74 system.
This  procedure  applies  to  the  installation  of systems rebuilt to
support one or more of the unbundled  system  components  as  well  as
installation of the distributed form.

If it is not necessary to support DBMS-10 and MCS-10  or  any  of  the
special configurations described in section 4 only the files mentioned
in the remainder  of  this  section  need  to  be  obtained  from  the
distribution  tape.   If  one  or  more of the unbundled components or
special configurations is to be supported please refer to section 4 of
this  document  for  details  of  required  files  and  procedures for
restructuring the system before installation.   Instructions  for  the
installation  of the unbundled components themselves are included with
the unbundled distribution packages.


First restore the DOCUMENTATION save set to DSK:
Then read the DOC and BWR files.

To do this use the following procedure:

A.  Mount the COBOL distribution tape on MTA0:

B.  Type the following commands:

                R BACKUP
                TAPE MTA0:
                INTERCHANGE
                DENSITY 1600 
                RESTORE *.*
                REWIND
                EXIT


To install COBOL and SORT use the following procedure:

A.  Mount the COBOL distribution tape on MTA0:

B.  Type the following commands:

                R BACKUP
                TAPE MTA0:
                INTERCHANGE
                DENSITY 1600 
                SKIP 1
                RESTORE *.EXE, C74LIB.REL, COBDDT.REL
                REWIND
                EXIT


The entire installation can then be accomplished with three COPY
commands of the general form:
COBOL-74 FOR V12C ON TOPS-10: INSTALLATION GUIDE                Page 9


In order to do the following copies one must be logged into [1,2]

     .COPY SYS: = *.EXE, COBDDT.REL, C74LIB.REL
     .COPY DOC: = *.DOC
     .COPY HLP: = *.HLP
COBOL-74 FOR V12C ON TOPS-10: INSTALLATION GUIDE               Page 10


4.0    SYSTEM REBUILDING


This section details how to rebuild all or part of the COBOL-74 system
in  order to support DBMS-10 and MCS-10, to change feature test switch
setting, or for maintenance purposes.

To simplify the building task  BLDCBL.CTL  reads  the  COBOL.TEC  file
which  contains  definitions  of  all the logical names used.  If this
file exists BLDCBL uses it to modify all the CTL files to produce  CTM
files  which  it  then  submits.   This allows the installation to use
private  packs  and  different  disk  areas  for  the  build.   It  is
recommended  that  the  same  logical  names be used and that the user
should edit COBOL.TEC to contain appropriate  definitions.   Similarly
BLDSRT.CTL  reads  SORT.TEC  if  it  exists  to  produce SORT.CTM from
SORT.CTL.  Once the CTM files have been produced they can be submitted
for  all  future rebuilds providing, of course, that the logical names
do not change.  It is recommended that installations  modify  the  TEC
files  rather than the CTL files since Digital will most likely modify
the CTL files with each release.
The logical names used by the CTL files are:  SYS:, REL:, UNV:
Digital must use field-image software to build a  release  tape,  thus
the  supplied TEC files use the device DEC:.  In general installations
do not have this device, thus SYS:  should not be redefined.   If  you
have  devices  REL:   and UNV:  they also do not need to be redefined,
otherwise they must be ASSIGNED to SYS:

COBOL-74 version 12C supports the following user installation settable
feature  assembly  switches:   DEBUG,  DBMS,  DBMS4  (DBMS  version  4
features) and DBMS6 (DBMS version 6 features)  MCS,  BIS,  and  ONESEG
(single segment compiler).  Other assembly switches are supported only
in their distributed position.  The  default  setting  for  the  DBMS,
DBMS4  DBMS6,  MCS,  and  BIS  switches  is  ON (1), and for DEBUG the
default setting is OFF (0).   This  represents  the  standard  default
configuration.

The supported switches may be  turned  on  or  off  by  setting  their
symbols  equal  to  1 or 0 in the universal file COBASM and rebuilding
portions of the system according to the instructions in the  following
sections.   COBASM  is  the  assembly  switch  definition file for all
system components.  A symbol equal to 1 means  the  switch  is  on,  a
symbol equal to 0 means the switch is off.

Rebuilding requires that all of the distributed files be copied to the
appropriate  disk  areas.   If  a total rebuild is to be done then the
appropriate build area can be cleaned up by  deleting  all  LOG,  REL,
MAP, UNV, etc.  files leaving only the control files.

Included on the tape is a sample COBOL.MIC.  If your system uses  mic,
then  this  file  can  be  modified  for your build.  However, if your
system does not have MIC then this file needs to be deleted.

4.1    Required System Software


In order to rebuild all or part of  the  COBOL  system  the  following
standard  system  software  is  required,  of the specified or a later
version.

     Software       Version
     --------       -------

     MACRO          53A(1173)
     LINK           4A(1220)
     MAKLIB         2A(67)
     CREF           53(53)
     UUOSYM.UNV     15(521)

COBOL-74 Version 12C will run under all monitors 7.02 or later as will
programs compiled with COBOL version 12C.
COBOL-74 FOR V12C ON TOPS-10: INSTALLATION GUIDE               Page 12


4.2    Standard Configuration


The standard distributed multi-segment compiler contains  support  for
all  DBMS-10  and  MCS-10 syntax.  This means that all of the reserved
words for DBMS-10 and MCS-10 are present in the standard configuration
of COBOL-74 Version 12C.  This eliminates the necessity for rebuilding
the COBOL compiler to get support for this unbundled component.

The standard distributed configuration also contains  an  object  time
system  and  a  series  of utility routines.  The standard distributed
configuration of the object time system includes full support for SORT
so  there  is  no  need  to run the SORT CTL file unless there are bug
fixes to apply to SORT.  The standard distributed configuration of the
object  time  system  does  not include support for DBMS-10 or MCS-10.
However rebuilding of the entire object time system is  not  required,
all  that  is  required  is  to  submit the additional control file as
specified in sections 4.3 and later..

In general it is not necessary to rebuild the entire COBOL  system  in
order  to configure systems supporting unbundled components or to make
patches to the existing system.  The instructions for  each  component
specify  any dependencies upon the state of other system components in
order that no more of the system need be rebuilt than necessary.   The
only  general  restriction  is  that  none  of  the component building
control files may be executed concurrently and that the  compiler  and
OTS  must  be built first or the .UNV files from a previous build must
be available for the other components.  The following  is  a  list  of
each  component  of  the  standard  configuration.  The list is in the
order in  which  the  control  files  for  each  component  should  be
submitted  if  all  components  are  being  built.  The list shows the
actual SUBMIT command which should be used for each control file,  and
as  long as the user is aware of the dependencies described, the order
of submitting them is not critical.  If you should wish to  build  the
whole  system,  just  submit  the file BLDCBL.CTL in COBOL-BUILD which
will then submit all the other .CTL/.CTM files in  the  correct  order
with  dependency  counts.   The  .CTM  files  are  only created if the
COBOL.MIC file has been deleted.

Note that there is a "chicken and egg" problem with  trying  to  build
from scratch a COBOL OTS containing either or both SORT and DBMS.  The
problem is that the LIBOL CTL file could build a complete OTS  in  one
step  if  only  the  SORT  and/or DBMS CTL files had already been run.
However these control files require that  LIBOL  be  run  first.   The
correct procedure is to first run LIBOL as part of the general rebuild
(use BLDCBL).  Then run SORT followed by DBMS.  Once the initial build
has  taken  place only the control file for the piece that has changed
need be rerun providing, of course, that nothing in the build areas is
deleted.   Thus  if  a  bug is fixed in COBOL SORT there is no need to
rerun the LIBOL control file, just run the SORT one.   Currently  only
the LIBOL and SORT CTL files have been fixed to do this.  The DBMS CTL
files have not yet  been  fixed,  they  still  require  a  version  of
C74LIB.REL not yet containing DBMS files.

Please be sure that you have at least 20,000 blocks free to begin this
procedure
To build the COBOL-74 compiler:

A.  Mount the COBOL distribution tape on logical MTA0:


B.  Type the following commands:


LOGIN to the COBOL-source area
                     REWIND MTA0:
                     R BACKUP
                     TAPE MTA0:
                     DENSITY 1600 
                     INTERCHANGE

C.  LOGIN to COBOL-BUILD. Modify COBOL.TEC, 
    DELETE *.LOG, then SUBMIT the required files.


     a.  The whole system
            SUBMIT BLDCBL.CTL

         Note, in general the various CTL files will not run unless
         modified. BLDCBL does this when it is submitted, it reads the
         CTL files and produces CTM files which it then SUBMITS. 

     b.  COMPILER
            SUBMIT COBOL.CTM/TIME:1:00:00/RESTART:YES
            Dependencies:  None

            Dependencies:  None

     d.  COBDDT
            SUBMIT COBDDT.CTM
            Dependencies:  INTERM.UNV and COMUNI.UNV

     e.  ISAM
            SUBMIT ISAM.CTM

     f.  LIBARY
            SUBMIT LIBARY.CTM
            Dependencies:  None

     g.  RERUN
            SUBMIT RERUN.CTM
            Dependencies:  COMUNI.UNV, FTDEFS.UNV and LBLPRM.UNV

     h.  CPYLIB
            SUBMIT CPYLIB.CTM
            Dependencies:  None


NOTE, there will be no SORT in the OTS built by this procedure  unless
the  file  SRTCBL.REL is in the SORT-BUILD area (this file is produced
by SORT.CTL).
See sec.  4.3.2 for instructions for installing SORT into the OTS.

Also, there will be no DBMS support in the OTS built by this procedure
unless  the  file  DBSCOB.REL  is in the DBMS-BUILD area (this file is
produced  by  DBMS.CTL).   See  sec.   4.3.1  for   instructions   for
installing DBMS into the OTS.

4.3    Non-Standard Configurations


The following sections  specify  what  rebuilding  of  the  system  is
required   in   order  to  produce  specialized  configurations.   The
instructions are divided by feature but they are easily combinable  to
provide  more  than  one  of the capabilities.  Refer to the preceding
section  for  specifics  when  instructed  to  rebuild   some   system
component.






4.3.1    DBMS-10 -




4.3.1.1    Completing Support For DBMS-10 -

If you have a standard configuration  Version  12C  COBOL-74  compiler
(i.e.   the  one  on  the  distribution  tape),  all that is needed to
complete support for DBMS-10 is to follow these instructions:

     1.   Include a copy of C74LIB.REL and C74SHR.REL in the same disk
         area as the contents of the DBMS-10 distribution tape.

     2.  Refer to DBMS10.DOC for DBMS-10 installation instructions.

     3.  If you already have built DBMS and are just changing SORT  or
         LIBOL  then it is just sufficient to run the appropriate SORT
         or LIBOL CTL file.





4.3.1.2    Removing Support For DBMS-10 -

The standard configuration of the  COBOL-74  compiler  comes  complete
with  support  for DBMS-10 , however, the object time systems will not
have DBMS-10 support.  This makes it much easier  to  install  DBMS-10
later.   However,  it does increase the size of the compilers slightly
and increases the number of reserved words.  If you do  not  want  any
DBMS-10  support  in  the  compilers,  it  is  possible to rebuild the
compilers turning off the DBMS, DBMS4, and DBMS6 switches.   This  can
be accomplished in the following manner:

     a.  Copy  the  contents  of  the  COBOL  distribution  tape  into
         appropriate disk areas.

     b.  Modify the universal file "COBASM.MAC" to include the  symbol
         definition "DBMS==0".

     c.  Rebuild the COBOL compiler.

If you later wish to reinstitute support for DBMS-10 in the  compiler,
follow  steps  a  and  c,  making sure that the symbol "DBMS" does not
appear in the universal file "COBASM.MAC".

4.3.2    SORT -


     a.  If COBOL-74 and SORT are all being rebuilt because  of  major
         changes  in  the configuration, then the correct procedure is
         to first submit BLDCTL.CTL and then SORT.CTL.
         BLDCTL.CTL creates the file required by SORT.CTL to  add  the
         SORT to C74OTS.
         On the other hand if a COBOL-74 OTS exists and only SORT  has
         been modified then it is sufficient to run only SORT.CTL.
         Similarly if SORT exists (i.e.  SRTCBL.REL) and COBOL-74  OTS
         has  been modified it is sufficient to run only LIBOL.CTL for
         the OTS.

     b.  SUBMIT SORT.CTL/TIME:0:30:00/RESTART:YES
         which will replace  the  existing  SORT  module  in  the  OTS
         (either  the original dummy one or an existing real one) with
         a newer real SORT.  It will  generate  modified  versions  of
         C74LIB.REL  and  C74O12.EXE.   It  will  try  to rename these
         modified files back to the area from which it got them  (note
         both  the file and UFD protection must be set to allow this).
         If, for any reason, this should fail they will be left in the
         SORT-BUILD  area.   It  will also build SORT.EXE which is the
         stand alone configuration.

     c.  Install the new SORT

             COPY SYS: = SORT.EXE
             COPY DOC: = SORT.DOC
             COPY HLP: = SORT.HLP






4.3.3    USER OTS ROUTINES -

COBOL-74 includes a facility allowing installations to add  their  own
special  purpose  MACRO  routines to C74LIB.REL.  This is accomplished
via a dispatch routine, loaded with the user  program  which  resolves
the  external  references  into references to a user dispatch table in
the OTS.  For routines requiring low segment storage there is  a  user
dynamic  (indexed)  low  segment  facility.   Refer  to USRDSP.MAC for
complete instructions.

The user  routines  are  added  to  C74LIB.REL  after  all  other  OTS
rebuilding but before installation on SYS:.

4.3.3.1    MCS -




4.3.3.2    Completing Support For MCS-10 -


If you have the standard configuration compiler (i.e.  the one on  the
distribution  tape),  it  is  not  necessary  to  rebuild  any  system
component, simply refer to the MCS-10 distribution package for  MCS-10
building and installation procedures.






4.3.3.3    Removing Support For MCS-10 -


The standard configuration of the compiler comes complete with support
for  MCS-10.   This  makes  it  much  easier  to install MCS-10 later,
however, it does increase the  size  of  the  compilers  slightly  and
increases the number of reserved words.  If you do not want any MCS-10
support in the compiler,  it  is  possible  to  rebuild  the  compiler
turning off the MCS switch.  This can be accomplished in the following
manner:


     a.  Copy  the  contents  of  the  COBOL  distribution  tape  into
          appropriate disk areas.


     b.  Modify the universal file "COBASM.MAC" to include the  symbol
          definition MCS==0.


     c.  Rebuild the COBOL-74 compiler.


If you later wish to reinstitute support for MCS-10 in  the  compiler,
follow  steps a and c, making sure that the symbol MCS does not appear
in the universal file "COBASM.MAC".

4.3.4    Single Segment Compiler -

It is possible to build a single segment compiler.  The compiler  will
require 110K to compile a minimal COBOL program.

     a.  Modify  COBASM.MAC   to   include   the   symbol   definition
         "ONESEG==1".

     b.  Rebuild the COBOL compiler.

     c.  This will produce a single segment compiler  CBL74.EXE  which
         can be copied to SYS:  instead of the multi-segment compiler.

     d.  The remainder of  the  system  is  installed  in  the  normal
         fashion.





4.3.5    Shareable RMS And OTS -

The normal method of using RMS is to have a shareable OTS and to merge
in  RMSCOB  at  run  time.   This results in each job that uses RMS in
having a non-shareable copy of RMSCOB.  If the majority  of  users  at
any  site  use  RMS this can result in a considerable waste of memory.
It is possible to build a high segment that contains both the OTS  and
RMSCOB, however then all users of COBOL-74 will get a larger OTS.

To do this use the program GPMSM which is on  the  DOCUMENTATION  save
set.
.R GPMSM
GPMSM>MERGE SYS:C74O12
GPMSM>MERGE SYS:RMSCOB
GPMSM>EXIT
.SSAVE C74O12

Then use this version of C74O12 in place of the original one.

5.0  COBOL-68 TO COBOL-74 CONVERSION UTILITY


The COBOL-68 to COBOL-74 conversion utility, 68274,  is  just  another
version  of  the  COBOL  compiler.  See 68274.MEM for more details.  A
working version of the utility  is  in  the  BINARY  save  set.   This
version  is  re-built  just  like  any other non-standard version (see
section 4.3).  Specifically:

     a.  Copy  the  contents  of  the  COBOL  distribution  tape  into
          appropriate disk areas.

     b.  Modify the universal file "COBASM.MAC" to include the  symbol
          definitions ANS68==1 and FT68274==1.

     c.  Submit COBOL.CTL to rebuild the conversion utility.

There is a HELP file and a MEM file in the DOCUMENTATION save set.
