You must use the Start Session screen for logging in to DECwindows, but you can substitute your own logo for the Digital logo by running an application that displays your logo.

To do this, you need to define a global symbol in the DECW$PRIVATE_APPS_SETUP.COM file and create a DCL command file that contains the commands to display your logo.

To display your own logo on the login screen, you need to:

• Create a command file (SYS$MANAGER:LOGO.COM, for example).
• Define the global symbol DECW$LOGINLOGO in SYS$MANAGER:DECW$PRIVATE_APPS_SETUP.COM, with its value set to the name of your command file. Note that this command file is run by the system account.

To create a custom logo, execute the following steps:

1. If the SYS$MANAGER directory does not contain a command file, copy the template file to a command file:

   $ COPY SYS$COMMON:[SYSMGR]DECW$PRIVATE_APPS_SETUP.TEMPLATE - _$ SYS$SPECIFIC:[SYSMGR]DECW$PRIVATE_APPS_SETUP.COM/LOG

2. Edit the file and define the symbol DECW$LOGINLOGO to point to the command file that displays your custom logo.
   Add the following line:

   $ DECW$LOGINLOGO == "SYS$MANAGER:MYLOGO.COM"

3. Create the command file that displays your logo. This needs to be the file name and directory specified in step 2. Note that the command file runs as a detached process under the SYSTEM account. Be careful not to give users access to the system through your custom logo. Do not run applications like FileView or DECterm as a custom logo.
   For example, the file SYS$MANAGER:MYLOGO.COM could contain this command to display the icosahedron that is shipped as an example program:

   $ RUN DECW$EXAMPLES:ICO

4. Restart DECwindows by running DECW$STARTUP, or reboot your workstation. Ending the session does not display the logo unless you execute the DECW$STARTUP command procedure that starts DECwindows.

   $ @SYS$STARTUP:DECW$STARTUP RESTART

   Caution Restarting the DECwindows server disconnects all current client processes.

   
   To restore the Digital logo, you need to remove the definition of DECW$LOGINLOGO from your DECW$PRIVATE_APPS_SETUP.COM file and restart DECwindows.

If you are a system manager, you can set up user accounts to run only certain applications. For example, you might want users to use only the Bookreader application.

This section describes the following three methods for setting up dedicated DECwindows accounts:

• Modifying the Session Manager command procedure
• Modifying the Session Manager executable file
• Modifying the Session Manager profile file

You can define the global symbol DECW$SESSIONCOM in the SYS$MANAGER:DECW$PRIVATE_APPS_SETUP.COM file so that when a user logs in, LOGINOUT runs a command file other than DECW$STARTSM.COM. This action bypasses Session Manager altogether.

In Example 4-1, DECW$SESSIONCOM is defined in DECW$PRIVATE_APPS_SETUP.COM to point to the private command procedure SYS$MANAGER: PRIVATE_SESSIONCOM.COM. The default command file is SYS$MANAGER:DECW$STARTSM.COM.

Because DECW$SESSIONCOM is defined in the system logical name table, it affects Session Manager startup for every user name. Your private command file must check the user name under which it is running and run the normal DECW$STARTSM.COM procedure for nondedicated accounts.

To modify the Session Manager command procedure:

1. Create the command procedure shown in Example 4-1.

   Example 4-1 Using a Private Session Manager Command File

   $ CREATE SYS$MANAGER:PRIVATE_SESSIONCOM.COM $! $! Check to see whether this is the dedicated DECwindows account. $! If it isn't, run the normal procedure to start Session Manager. $! $ username = F$USER() $ IF F$LOCATE("BOOK_READER", username) .NE. F$LENGTH(username) - THEN GOTO dedicated $! $! Normal, nondedicated DECwindows login $! $ @SYS$MANAGER:DECW$STARTSM $ EXIT $! $! Dedicated DECwindows login. Run Bookreader and then exit. $! $ dedicated: $! $ RUN SYS$SYSTEM:DECW$WSINIT $ display = F$TRNLNM("DECW$DISPLAY") $ RUN/DETACHED/OUTPUT='display' SYS$SYSTEM:DECW$MWM (1) $ RUN SYS$SYSTEM:DECW$BOOKREADER $ endsession := $DECW$ENDSESSION (2) $ endsession -noprompt (3) $ STOP/ID=0 (4)

   1. DECW$MWM is the Motif Window Manager. Its SYS$OUTPUT definition needs to be set to the translation of DECW$DISPLAY so that DECW$DISPLAY is defined correctly in the detached process.
   2. DECW$ENDSESSION resets the server and displays a Start Session dialog login box.
   3. The -noprompt qualifier prevents DECW$ENDSESSION from asking the user to confirm whether to end the session. (If the user cancels the End Session operation, the workstation will be unusable because Bookreader will exit and the login box will not be displayed.)
   4. STOP/ID=0 logs out the process without writing an error message to SYS$OUTPUT.
2. Define the DECW$SESSIONCOM symbol in DECW$PRIVATE_APPS_SETUP.COM as follows:

   $ DECW$SESSIONCOM :== SYS$MANAGER:PRIVATE_SESSIONCOM.COM

   
   If SYS$MANAGER:DECW$PRIVATE_APPS_SETUP.COM does not already exist, create it as follows from the template file:

   $ COPY SYS$MANAGER:DECW$PRIVATE_APPS_SETUP.TEMPLATE - _$ SYS$COMMON:[SYSMGR]DECW$PRIVATE_APPS_SETUP.COM

3. Restart DECwindows by entering the following command:

   $ @SYS$MANAGER:DECW$STARTUP RESTART

   
   This step is necessary for the changes to DECW$PRIVATE_APPS_SETUP.COM to take effect.
4. Log in to the dedicated account on a DECwindows system.
   After entering the user name and password of the dedicated account, Bookreader starts and Session Manager is not displayed. When the user exits from Bookreader, the PRIVATE_SESSIONCOM.COM procedure ends the session operation and then logs out. The End Session command displays the Start Session screen.

You can define DECW$SESSIONMAIN in the SYS$MANAGER: DECW$PRIVATE_APPS_SETUP.COM file so that DECW$STARTSM.COM runs the specified command file instead of DECW$SESSION.EXE. Session Manager reads resource files and executes login command files but does not display the Session Manager menu bar. With this method, ensure that the End Session command does not prompt for confirmation.

When DECW$STARTSM.COM starts (that is, if DECW$SESSIONCOM has its default value), it starts Session Manager by executing the DCL command that is stored in the logical name DECW$SESSIONMAIN. To define this logical name, edit SYS$MANAGER: PRIVATE_APPS_SETUP.COM so that it defines the global symbol DECW$SESSIONMAIN as the DCL command to execute.

This method is similar to the one described in the Section 4.3.3.1 except that, with this method, DECW$STARTSM.COM executes the SYLOGIN.COM, LOGIN.COM, DECW$SYLOGIN.COM, and DECW$LOGIN.COM command procedures. Also, DECW$STARTSM.COM executes DECW$WSINIT.EXE, so the private command procedure does not need to do so.

To modify the Session Manager executable file:

1. Create the command procedure shown in Example 4-2.

   Example 4-2 Modifying the Session Manager Executable File

   $ CREATE SYS$MANAGER:PRIVATE_SESSIONMAIN.COM $! $! Check to see whether this is the dedicated DECwindows account. $! If it isn't, run the normal procedure to start Session Manager. $! $ username = F$USER() $ IF F$LOCATE("BOOK_READER", USERNAME) .NE. F$LENGTH(USERNAME) - THEN GOTO dedicated $! $! Normal, nondedicated DECwindows login $! $ RUN SYS$SYSTEM:DECW$SESSION $ EXIT $! $! Dedicated DECwindows login. Run Bookreader and then exit. $! $ dedicated: $! $ display = F$TRNLNM("DECW$DISPLAY") $ RUN/DETACHED/OUTPUT='display' SYS$SYSTEM:DECW$MWM (1) $ RUN SYS$SYSTEM:DECW$BOOKREADER $ endsession := $DECW$ENDSESSION (2) $ endsession -noprompt (3) $ STOP/ID=0 (4)

   1. DECW$MWM is the Motif Window Manager. Its SYS$OUTPUT definition needs to be set to the translation of DECW$DISPLAY so that DECW$DISPLAY is defined correctly in the detached process.
   2. DECW$ENDSESSION resets the server and displays a new Start Session screen.
   3. The -noprompt qualifier prevents DECW$ENDSESSION from displaying the End Session prompt. (If the user cancels the End Session prompt, the workstation will be unusable because Bookreader will exit and the Start Session screen will not be displayed.)
   4. STOP/ID=0 logs out the process without writing a message to SYS$OUTPUT.
2. Define the DECW$SESSIONMAIN symbol in DECW$PRIVATE_APPS_SETUP.COM.
   Edit this command procedure to define DECW$SESSIONMAIN. Note that the symbol must be defined as a DCL command (unlike DECW$SESSIONCOM, which is defined as the name of a command procedure).

   $ DECW$SESSIONMAIN :== @SYS$MANAGER:PRIVATE_SESSIONMAIN.COM

   
   If SYS$MANAGER:DECW$PRIVATE_APPS_SETUP.COM does not already exist, create it as follows from the template file:

   $ COPY SYS$MANAGER:DECW$PRIVATE_APPS_SETUP.TEMPLATE - _$ SYS$COMMON:[SYSMGR]DECW$PRIVATE_APPS_SETUP.COM

3. Restart DECwindows by entering the following command:

   $ @SYS$MANAGER:DECW$STARTUP RESTART

   
   This step is necessary for the changes to DECW$PRIVATE_APPS_SETUP.COM to take effect.
4. Log in to the dedicated account on a DECwindows system.

After entering the user name and password of the dedicated account, Bookreader starts and the Session Manager menu bar is not displayed. When the user exits Bookreader, the PRIVATE_SESSIONMAIN.COM procedure performs an End Session operation and then logs out. The End Session command displays a DECwindows Start Session screen.

4.3.3.3 Modifying the Session Manager Profile File

This method starts Session Manager normally, but the system manager customizes its menus to remove any applications that are not started automatically. By removing certain applications, you can limit user access to applications.

With this method, the Session Manager menu bar is displayed, and the user can interact with whatever dialog boxes the system manager does not disable.

To modify the Session Manager profile file:

1. Log in to the dedicated account on a DECwindows system.
   When you enter the user name and password of the dedicated account, Session Manager starts.
2. Add the applications to the automatic startup list that you want to be displayed when a user logs in.
   Choose Automatic Startup... from the Session Manager Options menu. Session Manager displays the Automatic Startup dialog box.
   Use this dialog box to remove any undesired applications, such as FileView, from the automatic startup list. (For more information about using the Automatic Startup dialog box, see Using DECwindows Motif for OpenVMS.)

   Note Do not remove Window Manager from the automatic startup list.

   
   For this example add Bookreader to the list and click on OK.
3. Remove Applications from the Session Manager menu bar.
   Choose Menu Bar... from the Session Manager Options menu. Session Manager displays the Menu Bar dialog box.
   Use this dialog box to remove the applications you do not want to be displayed. (For more information about using the Menus dialog box, see Using DECwindows Motif for OpenVMS.)
   Click on OK to save your changes and to dismiss the dialog box.
4. Choose Save Session Manager from the Session Manager Options menu to save your menu bar settings.
5. Remove any menu items that you do not want to be displayed on the Options menu.
   Choose Menus... from the Session Manager Options menu and remove the following menu items from the Session Manager Options menu:
   • Automatic Startup...
   • Menus...
   • Menu Bar...
   • Save Session Manager
   
   You should also remove any other menu items that you do not want users to have access to in the dedicated account, such as Security.
   After removing the items, click on OK to dismiss the dialog box and to save your menu settings.
6. Choose End Session from the Session Manager Session menu.
   Session Manager logs you out of the dedicated account and displays the DECwindows login box.
7. Log back in to the dedicated account.

To test your changes, log in to the dedicated account from the DECwindows login box. Bookreader and Session Manager should start up by default, and you should not be able to start any other application. To log out, choose End Session from the Session Manager menu.

If you decide to make the account nondedicated again, or if you want to make changes in a dialog box that you have removed from the system menu bar, delete or rename the file VUE$PROFILE.VUE$DAT in the dedicated account's SYS$LOGIN directory.

4.4 Modifying Session Manager Behavior

You can modify the behavior of the DECwindows Session Manager by using several logical names. These logicals are not normally used; however, they may help in special circumstances, such as running two Session Managers on the same system. Table 4-2 lists the logicals and their meaning.

You can define these logicals in a DECterm or in the login command files (SYSLOGIN, LOGIN, DECW$LOGIN). To set any of these logical, define the logical name to any value, as in the following example:

$ DEFINE DECW$VUENOAUTOSTART 1

Most DECwindows applications provide dialog boxes that contain options for customizing your DECwindows environment and saving your settings. For example, using Session Manager Options menu, you can look at many predefined settings and then choose and save new settings.

However, not all applications provide dialog boxes for changing and saving settings. For example, some applications let you change and save the size or location of the application's main window and others do not. To change and save settings that are not available from dialog boxes, you can specify resources in a DECW$XDEFAULTS.DAT file.

To use resources to change application settings, create a file (DECW$XDEFAULTS.DAT) in the directory specified by the logical name DECW$USER_DEFAULTS. In this file, specify the resources for the application settings you want to change. Alternatively, if your changes are specific to one application, you can modify that application's resource file (for example, DECW$MAIL.DAT).

Note that each resource specification in the DECW$XDEFAULTS.DAT file follows explicit syntax rules. For more information about the resource syntax, see the VMS DECwindows Guide to Xlib (Release 4) Programming: MIT C Binding or X Window System.

See Using DECwindows Motif for OpenVMS for resource information for the following applications:

• Bookreader
• Calculator
• Calendar
• Cardfiler
• CDA Viewer
• Clock
• DECterm
• FileView
• Session Manager
• LinkWorks Manager
• Mail
• Motif Window Manager

This section describes how to define print formats and lists the logical names and associated print formats for DECwindows Motif software. Depending on your configuration, DECwindows Motif customization tasks can include defining logical names to specify print formats.

Before you start up the system, edit the OpenVMS startup procedure to define the logical names that associate print queues with print formats. This startup procedure will subsequently call the DECwindows Motif startup procedure. You can also add these logicals to your login command file.

4.6.1 Defining Print Formats

Many DECwindows Motif applications use the Print dialog box to queue files or screens to a printer. By default, all printing devices on the system are displayed in the Printer list box. However, print queues can be associated with print formats through the definition of logical names. You define the logical name in the OpenVMS startup command procedure before the call to the DECwindows Motif startup procedure. Separate the list of print queues with commas or spaces, with the first queue being the default choice.

You can customize the list of printer queues displayed in the Print dialog box by defining any of the logical names in Table 4-3. This method is faster than making the Print dialog box derive the names of all the queues on the system, most of which do not apply to the print format under consideration. The following example shows how to define logical names for print formats in the OpenVMS startup files:

    $ Define DECW$PRINTER_FORMAT_TEXT   "CLUSTER_LN03,CLUSTER_PRINT, -
    _$ ANSI_ARTWRK,ANSI_PROTON"
    $ Define DECW$PRINTER_FORMAT_LINE   "CLUSTER_PRINT"
    $ Define DECW$PRINTER_FORMAT_ANSI2  "CLUSTER_LN03,ANSI_ARTWRK,ANSI2_PROTON"
    $ Define DECW$PRINTER_FORMAT_ANSI   "CLUSTER_LN03,ANSI_ARTWRK,ANSI_PROTON"
    $ Define DECW$PRINTER_FORMAT_PS     "PS_ARTWRK,PS_PROTON"
    $ Define DECW$PRINTER_FORMAT_REGIS  "SYS$NULL"

For example, if DECW$PRINTER_FORMAT_ANSI2 is defined as CLUSTER_LN03, ANSI_ARTWRK, ANSI2_PROTON, then when you select ANSI2 from the Print Format list box, only CLUSTER_LN03, ANSI_ARTWRK, and ANSI2_PROTON are shown in the Printer list box, with CLUSTER_LN03 being the default choice.

4.6.2 Logical Names and Print Formats

Table 4-3 lists the logical names and the associated print formats in the DECwindows Motif product.

You can define the logical names in systemwide logical name tables and users can override the logicals when necessary.
