1: Install DECdx on TOPS-20
Introduction
This chapter explains how to install DECdx Version 1.0 on a
TOPS-20 system. Installation takes about 15 minutes.
DECdx Installation Requirements
The following are needed to install DECdx:
oo A TOPS-20 system with Version 5.1.
oo System manager privileges.
oo About 350 pages of disk space during installation and 130
pages after installation.
oo TOPS-20 Software Installation Guide.
oo This installation manual, which is also available on-line
in file DDXINS.MEM.
oo DECdx Version 1.0 software on magnetic tape, MT9 1600,
order number QT709-AM.
The magnetic tape volume is labeled DDX. Check that your kit
contains the volume listed in the bill of materials.
To install DECdx on your system, you must also know how to mount
the magnetic tape in the tape drive.
Preparing to Install DECdx
NOTE: The instructions in this manual assume that you are using
the operator's console terminal (CTY), but it is possible to
perform the installation from another terminal.
To prepare for installation:
1 Type <CTRL/C> to start a job at your terminal. You get a
message and prompt similar to this:
Installation-test System, TOPS-20 Monitor 4(2644)
@
2 Log into a privileged account.
@LOGIN Username password <RETURN>
3 Invoke the OPR program.
@ENABLE <ESC> (CAPABILITIES) <RETURN>
$OPR <RETURN>
OPR>
4 Find a tape drive you can use for mounting the DECdx tape.
For example:
OPR>SHOW STATUS TAPE-DRIVE/ALL <RETURN>
OPR>
7:59:33 --Tape Drive Status--
DRIVE STATE VOLID REQ# JOB# USER
----- ----- ----- ---- ---- ----
MTA0: Unloaded
AVR: Yes
MTA1: In Use DEK 31 45 MARTIN
AVR: Yes, Write: Yes, Unlabeled
MTA2: Loaded
AVR: Yes, Write: Yes, Unlabeled
OPR>
5 Mount the tape containing the files on the magnetic tape
drive. Remember to press the ON LINE button after mounting
the tape.
6 Protect the free tape drive from use by timesharing users by
making it unavailable. The following example uses drive
number 0, but you can specify any drive that is not in use at
the moment.
OPR>SET TAPE-DRIVE MTA0: UNAVAILABLE <RETURN>
Enter text and terminate with ^Z
7 Type a message such as INSTALLING UNBUNDLED SOFTWARE and type
<CTRL/Z>.
8 Return to the TOPS-20 command level by using the PUSH
command.
OPR>PUSH <RETURN>
TOPS-20 Command processor 4(514)
$
Installing DECdx
1 Assign a magnetic tape drive to your job. The following
example uses drive number 0, but you can use any free drive.
$ASSIGN <ESC> (DEVICE) MTA0: <RETURN>
$
If the drive has already been assigned, return to step 4 of
the preparation procedure (above) and locate an alternate
device.
2 Use the DUMPER routine to transfer the files from the
magnetic tape to a temporary working area. The following
examples assume the working directory is PS:<OPERATOR> and
the public directory is PS:<SUBSYS>.
$DUMPER <RETURN>
DUMPER>
3 Tell DUMPER which tape drive to use. Use the number of the
drive you assigned in step 1.
DUMPER>TAPE <ESC> (DEVICE) MTA0: <RETURN>
DUMPER>
4 Rewind the tape to the beginning.
DUMPER>REWIND <RETURN>
DUMPER>
5 Restore the documents to directory PS:<OPERATOR>. You may
choose a directory other than OPERATOR. An empty directory
is not necessary because the DDXBLD command file
automatically deletes the binary relocatable files after they
are linked into an executable file, DDX.EXE (see step 10).
DUMPER>RESTORE <ESC> (TAPE FILES) PS: <ESC> <*>*.*.* (TO)
PS:<OPERATOR> <RETURN>
DUMPER TAPE # 1, <DOCUMENTS>, WEDNESDAY, 5-OCT-83 1741
LOADING FILE(S) INTO PS:<OPERATOR>
END OF SAVESET
DUMPER>
Two files should be loaded at this point:
1) DDXINS.MEM, the TOPS-20 Installation and Information
manual; and
2) DDXRLS.MEM, the TOPS-20 Release Notes.
If you do not see the message LOADING FILE(S) INTO
PS:<OPERATOR>, then no files are being restored from tape.
Rewind the tape and try again (steps 4 and 5). Be sure that
you mounted the correct tape and that the tape drive is
on-line.
6 Restore the binary files to PS:<OPERATOR>. About 75 files
will be loaded with this command.
DUMPER>RESTORE <ESC> (TAPE FILES) PS: <ESC> <*>*.*.* (TO)
PS:<OPERATOR> <RETURN>
DUMPER TAPE # 1, <BINARY>, WEDNESDAY, 5-OCT-83 1743
LOADING FILE(S) INTO PS:<OPERATOR>
END OF SAVESET
DUMPER>
7 Restore the Help files to PS:<HELP> with the RESTORE command:
DUMPER>RESTORE <ESC> (TAPE FILES) PS: <ESC> <*>*.*.* (TO)
PS:<HELP> <RETURN>
DUMPER TAPE # 1, <HELP>, WEDNESDAY, 5-OCT-83 1745
LOADING FILE(S) INTO PS:<HELP>
END OF SAVESET
DUMPER>
8 All the DECdx files are installed at this point. If you want
to install other unbundled software products, go back to step
4 of the preparation procedure. Repeat the procedure, naming
the next product to install. Otherwise, exit the DUMPER
routine and return to TOPS-20 command level.
DUMPER>UNLOAD <RETURN>
DUMPER>EXIT <RETURN>
$
9 Deassign the tape drive.
$DEASSIGN <ESC> (DEVICE) MTA0: <RETURN>
$
10 Link the binary relocatable file into an executable file:
@CONN <ESC> (TO DIRECTORY) PS:<OPERATOR>
$TAKE <ESC> (COMMANDS FROM) PS:<OPERATOR>DDXBLD.CMD <RETURN>
The system responds with the following:
LINK: Loading
Exit
DDX.EXE.1 Saved
End of DDXBLD.CMD.1
$
The command procedure, DDXBLD, deleted the DECdx binary
relocatable files from <OPERATOR>, or the directory you
specified, and displayed a list of the deleted files.
11 Rename or copy the .EXE file from the working area to the
public subsystem area.
$RENAME <ESC> (EXISTING FILE) DDX.EXE.* <ESC> (TO BE)
PS:<SUBSYS>DDX.EXE.1 <ESC> !NEW FILE! <RETURN>
DDX.EXE.1 => <SUBSYS>DDX.EXE.1 [OK]
$
12 Delete the .EXE file if the file was copied to the public
area.
$DELETE DDX.EXE <RETURN>
Errors
If you get errors using DUMPER, refer to the description of
DUMPER in the TOPS-20 User Utilities Guide (AA-D850A-TM). For
more information on crash recovery, see the TOPS-20 Software
Installation Guide (AA-M229A-TM).
After Installing DECdx
1 Release the tape drive for use by other users and exit the
OPR program. This example uses device 0; substitute your
device number.
$POP <RETURN>
OPR> SET TAPE-DRIVE MTA0: AVAILABLE <RETURN>
OPR> EXIT <RETURN>
@
2 Remove the tape from the drive, and store it in a safe place
for possible future use.
Release Notes
The DECdx/TOPS-20 Release Notes, which were printed during step 5
of the installation procedure, are on-line in the file
DDXRLS.MEM. Please read the Notes for information on
documentation and software problems.
2: User Support
User Support at Start-up
In general, DECdx users are familiar with the WPS menu format.
To support this user, DECdx uses WPS-like menus as the user
interface. User responses to DECdx menus and prompts initiate
DECdx functions.
The system manager must support the user by:
oo Assigning a user name, a password, and an account number.
oo Establishing a user directory.
oo Supplying WPS communications settings information (baud
rate, parity, data/stop bits) so that communication takes
place.
oo Helping the WPS user with TOPS-20 commands and error
messages.
The user will find all necessary information for running DECdx in
the Getting Started card (AV-P146A-TK).
The DECdx options and their use are described in the DECdx User's
Guide (AA-U153A-TK). Information specific to the TOPS-20
operating system is also provided.
On-line assistance is available by typing H at the DECdx Menu.
Help for each option consists of the definition, why the option
is used, how it is used, any shortcuts, and where to get more
information.
File Protection Requirements
The DECdx index must be protected with group write privileges for
the documents to be written to or read.
Set up the DECdx index with this default protection code:
@SET FILE PROTECTION <ESC> (of files) INDEX.DX.* <ESC> (to)
777700
INDEX.DX.1 [OK]
@
Conversion of DX/TOPS-20 Documents
When users select the ON option, they see this message:
Old format files will be deleted following successful
conversion.
If you wish to make backup copies, do not proceed with
conversion.
This message refers to files created under the previous
DX/TOPS-20 product (Version 1.0). The system manager may have to
help the user by verifying that backups of the files exist, or by
creating a separate directory for copies of the old-format files.
The DECdx installation procedure does not delete the old WNDX
file (the DX/TOPS-20 index). The ON (Old-to-New conversion)
option uses the WNDX file to assign document names during a
multiple document conversion process. After successful multiple
conversion, the ON option deletes the old WNDX file.
More information on DX/TOPS-20 and Old-to-New conversion is given
in the DECdx User's Guide (AA-U153A-TK).
Easycom
Easycom is a command file used by DECmate II systems to automate
some of the steps required in certain procedures, such as logging
on and getting to the DECdx Document Transfer Menu.
The DECdx documentation does not mention any changes to
procedures that might be modified by Easycom. If Easycom is used
to automate DECdx procedures, the system manager must explain the
changes to users.
Continuing User Support
Once users are familiar with DECdx, they should require very
little assistance from the system manager. However, several
error messages in the on-line assistance direct the user to the
system manager for help. Except for the problem of unlocking
documents (see the next section), the error messages deal with
system-specific problems such as file protection interference and
insufficient disk space.
Unlocking Documents
A document may remain locked after the user has finished adding,
printing, converting (File-to-Document or Old-to-New options),
deleting or transferring it. This abnormal locked condition is
especially likely to occur when the user presses CTRL/C to exit
the Read, Print or Document-to-File options. Until the document
is unlocked, anyone trying to access the document receives this
error message:
That document is in use by someone else right now.
The on-line assistance for this error suggests the user see the
system manager if the document remains locked when no one is
using it.
To unlock the document follow this procedure:
1) Check the user's DECdx index. The word "Locked" should
appear in the File Lock column for the document.
2) Verify that no one is using the document.
3) At the user's DECdx Main Menu, type the word CORRECT and
the name or number of the locked document. For example:
CORRECT May Claims Mailing List
4) Check the index to make sure "Locked" has been replaced
with "Free".
Note that the CORRECT command is an invisible menu option.
However, because the system manager may want to restrict its use,
CORRECT is not documented in the DECdx User's Guide, the Getting
Started Card, or the on-line assistance.
Error Tracing
DECdx provides an error Traceback feature. The system manager
can, immediately after an error occurs, view the messages
associated with that error by typing TRACE from the DECdx Menu.
The TRACE command displays all messages on the error stack. The
system manager can use available RMS documentation to evaluate
RMS errors.
Temporary Files
Temporary files are created two ways:
oo The user presses CTRL/C to stop a Top, Bottom, or
Overwrite procedure.
oo The user exceeds the disk quota in the process of adding
text to an existing document.
The following sections explain how to deal with temporary files.
Temporary Files Caused by use of CRTL/C
Temporary files may result when the user presses CTRL/C to exit
the options Add, FD, and Transfer after choosing Top, Bottom or
Overwrite. (Temporary files created by exiting DF are discussed
later). If a temporary file is created, the DOCnnn.DX file is
missing from the user's directory, and the DECdx index has this
message after the document name: "This document can not be found
in the current area".
The user's directory has one of these temporary files:
oo TMPnnn.DX if Top or Overwrite was exited
oo BTMnnn.DX if Bottom was exited
To restore the DOCnnn.DX file, rename the temporary file. The
original file, plus the new information, is in the temporary
file, which DECdx did not have time to rename before the user
pressed CTRL/C.
If the user exited after choosing Top or Overwrite, check the
directory for a temporary file in the format TMPnnn.DX, where
"nnn" is the document number of the missing document (see the
DECdx index for the document number if there are several
temporary files). Rename the TMPnnn.DX file to DOCnnn.DX. For
example:
@Rename TMP088.DX DOC088.DX <RETURN>
If the user exited after choosing Bottom, check the user's
directory for the temporary file, BTMnnn.DX, where "nnn" is the
document number of the missing document. Rename the BTMnnn.DX
file to DOCnnn.DX. For example:
@Rename BTM023.DX DOC023.DX <RETURN>
The use of CTRL/C to exit the DF (Document-to-File) option during
a Top, Bottom or Overwrite Procedure may also result in a
temporary file of the format TMPnnn.DX. The TMPnnn.DX file is
the original file to be converted, together with new information,
as modified by the Top, Bottom or Overwrite choice. The
converted file disappears from the user's directory. DECdx did
not have time to rename the file before the user stopped the
conversion with CTRL/C.
To reinstate the file, rename the temporary file. For example:
@Rename TMP034.DX Status.rpt <RETURN>
Temporary Files Caused by Insufficient Disk Space
If DECdx cannot add text to an existing file using the Top,
Bottom or Overwrite, options due to insufficient disk space, a
temporary file is created. The temporary file, in the format
TMPnnn.DX, is a partial file that contains whatever text was
added before the disk quota was exceeded.
Although the system indicates that the procedure may be resumed
after files are expunged, this is not the case. The user has to
restart the procedure after more disk space is acquired. The
temporary file is superseded after successful completion of the
task.
The temporary file may be deleted to acquire extra space. Before
deleting the file, verify that it is the right temporary file by
finding the corresponding DOCnnn.DX file, where "nnn" is the same
in both files.
3: Notes for the System Manager
What is DECdx?
DECdx V1.0 is a layered software product that runs on the TOPS-20
operating system, Version 5.1. DECdx provides WPS document
transmission over point-to-point data communication links between
DIGITAL word processing systems (WPS) and DIGITAL host systems.
In addition, DECdx provides options for manipulating WPS
documents that are on the host.
DECdx allows users to:
oo Transfer WPS documents to the host, preserving the WPS
formatting.
oo Create files on the host and then transfer those files to
the WPS for editing.
oo Access the data processing and file management
capabilities of the host.
oo Store large documents on the host.
oo Share documents.
For basic information on DECdx, see the DECdx/TOPS-20 Version 1.0
Software Product Description, SPD 21.36.00.
Document Transfer
The purpose of DECdx software is to facilitate transfer of
WPS-format documents to a host and to use those documents on the
host. The X option transfers documents by using the DX protocol;
the Document-to-File (DF) option translates WPS-format documents
to ASCII-format files.
The WPS system also offers a CX (Character transfer) option that
has settings such as HD (Host to Document) and DH (Document to
Host). The WPS user should choose the CX option when:
oo There is no need to preserve the special WPS-format
characters in a document, and
oo The user does not want to use the special DX
error-detecting protocol.
For example, use the WPS CX option with the HD/DH settings to
move source (program) files from the host to the WPS and vice
versa.
Document Compatibility
DECdx V1.0 running on TOPS-20 is compatible with DECdx V1.0
running on:
oo VMS
oo RSX-11M or RSX-11M PLUS
oo RSTS/E
oo TOPS-10
DECdx makes WPS documents compatible among the six operating
systems. Users can move documents to other host systems by
magnetic tape and use those documents at the new host with no
compatibility problems.
Multiuser Software
When more than one user uses the same account, DECdx detects and
prevents multiple user updates of the same document. Limited
access prevents users from losing data due to simultaneous access
collisions.
Supersession
DECdx Version 1.0 supersedes DX/TOPS-20 Version 1.0.
How DECdx Differs From DX/TOPS-20 V1.0
If the host previously ran DX/TOPS-20 Version 1.0, read this
section to understand the differences between that older product
and DECdx.
New Features
oo Compatibility -- Documents stored under TOPS-20 using
DECdx are compatible with DECdx documents on VMS, RSX-11M
and RSX-11M PLUS, RSTS/E, and TOPS-10.
oo Multiple users capability -- DECdx controls multiple users
access to documents in the same storage area (directory)
on TOPS-20. DECdx also controls document access through
the DECdx index function to avoid document-access
collisions.
oo ON (Old-to-New) conversion option -- The ON option lets
users of DX/TOPS-20 V1.0 convert existing documents to
DECdx format.
oo R (Read) option -- The Read option on the DECdx Menu lets
the user display the contents of a document.
oo A (Add) option -- The Add option on the DECdx Menu
enhances document transfer on the host. The user can now
add WPS documents to his/her own DECdx index from other
users on the host.
oo F (Finished) option -- The Finished option on the DECdx
Menu lets the user exit from DECdx to TOPS-20 command
level.
oo Traceback (TRACE) feature -- Some error messages direct
the user to the system manager for help. The system
manager can use the Traceback feature for more information
on the error. The Traceback feature is described under
Error Tracing in Chapter 2.
oo CORRECT -- A document may be unlocked by typing the word
CORRECT and the document name or number at the DECdx Main
Menu. See the section, Unlocking Documents, in Chapter 2
for detailed information.
Functional Changes
Debugging -- DECdx is not supplied as source code, therefore
DEBUG code is no longer necessary and is not included.
Simpler Interface -- The user does not have to invoke each
function with a separate command. The user invokes DECdx (if it
is defined as a foreign command) with the command DDX and then
selects the appropriate option from the DECdx Menu. Most users
are familiar with DIGITAL WPS menus and should feel comfortable
using DECdx menus.
Command Line Parser -- DECdx parses command lines passed by
TOPS-20. Command line parsing:
oo Permits execution of a function from the operating system
level. With DDX defined as a foreign command, the user
can specify commands as:
@DDX <menu option> <parameter1> <parameter2><RETURN>
For example:
@DDX FD Q1.RPT First Quarter Results<RETURN>
oo Supports "type-ahead" similar to WPS. User-typed
characters are buffered, so that DECdx executes the
commands as soon as processing allows.
Document Numbers -- The document numbers now range from 1 to 200,
rather than from 2 to 999.
Reserved Extension -- The reserved file extension for DECdx is
.DX, as opposed to the .W11 extension under DX/TOPS-20. The DF
conversion function uses either a null file extension or a
user-supplied file extension.
H (Help) option -- The Help option offers more extensive on-line
assistance than was available through DX/TOPS-20.
Error Handling -- For failures within the product (DECdx) or the
environment (TOPS-20), the DECdx user sees an error message. By
typing H and pressing RETURN, the user may read the on-line
assistance for an explanation.
If the user goes directly to the on-line assistance, DECdx
terminates the current process. The user has to return to the
DECdx Menu and reselect the option.
The system manager can use the Traceback feature for more
information on errors. The Traceback feature is described under
Error Tracing in Chapter 2.
Conversion -- The DF (Document-to-File) and FD (File-to-Document)
options on the DECdx Menu let the user convert documents from
ASCII to WPS and WPS to ASCII formats. These options simplify
the earlier WFLX program available under DX/TOPS-20.
The FD and DF options have these characteristics:
oo Prompt for file name -- The user is always prompted for
and must supply the file name first, whether the
conversion is a document-to-file or file-to-document
conversion.
oo Text conversion default -- Under DF, the user is no longer
prompted for a file type. DECdx assumes conversion to a
text file. The user can no longer convert to a BASIC-PLUS
or source program file. The DF conversion function uses
either a null file extension or whatever file extension
the user defines.
oo WPS-format similarity -- Under DX/TOPS-20, the user saw a
prompt to change the default ruler during FD conversion.
Now the host default ruler is inserted automatically into
the converted document without changing the appearance of
the original file.
Under DF, the prompt for designating tabs or spaces in the
converted file has been eliminated.
Index -- The DECdx index now resembles a WPS index. The
documents are displayed five at a time, instead of scrolling
continuously. The host directory now lists the DECdx index as
INDEX.DX, rather than DOC001.W11.
The DECdx index is a RMS indexed file of formatted records. The
user cannot access the DECdx index as a document and should not
edit INDEX.DX on the host. However, the user can print the DECdx
index by using the PHOTO utility.
The WDNX product used a version number of 0 to indicate a missing
or delete-protected document. The DECdx index has the message
"This document can not be found in the current area" when the
DECnnn.DX file has been deleted. Delete-protected files are not
indicated. DECdx does not have Version Number or Time Elapsed
columns in the index.
Delete -- The Delete option (which replaces the WDEL program) now
closely resembles the WPS deletion procedure. The user sees the
first eight lines of the document to confirm the deletion.
Printing -- The Print option (which replaces the WLPT program)
lets the user print the document without exiting to TOPS-20 and
issuing the PRINT command. The document prints immediately
unless the user specifies PD No. The new DECdx Print Menu allows
the user to change settings in a manner similar to WPS, rather
than in response to prompts, as under DX/TOPS-20.
Also, note these changes to the default print settings:
Old Setting New Setting
EX 0 DS No
DD LP --
-- PD Yes
-- SL No
This value range has been changed:
Old Range New Range
CP 1 to 999 CP 1 to 10
Under the Print option, DECdx creates a printable file,
PRnnn.DAT, where "nnn" is the document number in the DECdx index.
DECdx deletes the PRnnn.DAT file after the document is printed
unless the user sets SL Yes.
The DX/TOPS-20 restriction of 60 printable lines per page no
longer applies.
