Header
The screen header is located at the top of the screen (the top three lines), and contains five elements, each of which is described here. The five elements are:
Program name (NMMGR/3000) and version number
Screen number and title
Data flag
Message field
Command window
Program Name and Version Number
The program name and version number are always displayed in a protected field at the top of the screen. (Protected means that information cannot be typed into the field.)Screen Number and Title
To the right of the program name and version number is the screen number followed by the screen title. Each screen number is unique for that screen. There is no significance to the order of the numbers. They are strictly for convenience in referencing information about a screen in various reference documents. Screen titles are also unique for each screen and will generally indicate the purpose and content of the screen.Data Flag
The data flag is a Yes or No indicator located in the upper-right corner of screens that contain data entry fields. The data flag indicates whether or not a data record has already been created for the screen. The data flag is an important indicator in cases where default information is supplied in the fields of a screen when a new configuration file is created. The information in the fields has not yet been saved, even though it may appear that the information on the screen is complete. If you want the information on the screen to become a part of the configuration, you must press the [Save Data] function key to create the actual data record. The data flag will change from N to Y, verifying that the data has been made part of the configuration file. Once a data record has been created for a screen, the data flag is set to Y whenever you return that screen.Message Field
The message field is the second line of the header and may contain one of two types of information:The action that this screen requires
An NMMGR error message
Command Window
Each screen includes a field labeled Command: that is located below the message field. This field, called the command window, accepts commands rather than accepting data. This is an unprotected field and is displayed in half-bright inverse video. You can enter the following types of commands in this window:NMMGR commands. The valid screen mode commands and their meanings are shown in Table 2-1 "NMMGR Screen Mode Commands". You can enter each command using the full command name or you can abbreviate the command by entering only the portion to the left of the bracket as shown in the table.
MPE commands.
NMMGR path commands. Direct path branching and brother branching are described in this chapter.
 |
NOTE: You must press [ENTER], not [RETURN], to execute the command. |
Main Window
The major portion of each screen lists menu choices, displays information and selection choices, and presents fields for entering or displaying information. With the exception of data entry fields, the information on the screen is protected against modification.
Path Name
On most screens that can be reached by direct path branching, the path name used to reach the screen is displayed in the upper-left corner of the main screen window. The path name consists of all the screen names between the root (top of the structure) and the current screen, with the names separated by periods.Data Fields and Menu Choices
Data can be entered only into unprotected fields. For screens with more than one unprotected field, the cursor automatically moves to the next unprotected field when you reach the end of the present field or if you press [TAB]. Generally, the [TAB] key is used to step through the fields from the top of the screen to the bottom. If you need to back up to a previous field, use the [SHIFT][TAB] key combination. For more information, consult you Terminal Reference Manual.
When menu choices are presented on the screen, they are usually associated with one of the function keys at the bottom of the screen. To select the menu item, press the function key that corresponds to the item.
Other screens, sometimes referred to as select screens, present a list of configured items in protected data fields. They also contain a data entry field into which you can type the name of one of the configured items and select it for modification. Alternatively, you can type in a new name for an item to be added to the list. Press a function key that lets you perform an action on the selected item (add, modify, delete, rename). Pressing the function key will cause the action to be performed and often will cause a new screen to be displayed, allowing you to modify or define the selected item.Configuration File Name
NMMGR displays the name of the configuration file that you are working on in the area called File: at the bottom of each screen. This name is shown as filename.group.acct in Figure 2-1 "Common Screen Elements". On an actual screen, the name of the file you created or opened at the Open Configuration/Directory File screen is displayed at this location on the screen. The file name is not an input field; to change the working file, use the Open Configuration/Directory File screen.Function Keys
Each NMMGR screen has a set of eight softkeys, or function keys, which vary in function from screen to screen. Some screens may use only a few function keys, while others have functions assigned to all eight keys. The [Prior Screen] and [Help] function keys are present in nearly all screens. Other softkeys are also present, depending on the purpose of the screen you are viewing. Some of the more common function keys are described here. For many screens, you can find information on that screen's function keys in the Help information associated with the screen.
Prior Screen Key
Except for a limited number of screens, such as the Error Information screen and the Guided Configuration screen, the [Prior Screen] key is the right-most function key, [f8]. With a few exceptions (as listed), the screen displayed when [Prior Screen] is pressed will always be the screen most recently visited prior to the current screen, regardless of the manner in which you reached the current screen. In order to show the correct screen, NMMGR maintains a prior screen list, which is a sequential list of the screens that have been displayed. Pressing [Prior Screen] displays the most recent screen in the prior screen list and removes that screen from the list. The most recent screen in the list is the screen that was visited just prior to the current screen, with five exceptions:When you display the Error Information screen, NMMGR does not put this screen in your prior screen list. Thus, pressing [Prior Screen] never transfers you to the Error Information screen, even if it was the latest screen you displayed.
After reaching the Validate screen in guided configuration, the prior screen becomes the screen with which you began the guided configuration.
If you use the command window to return to a screen already visited, NMMGR drops any screens visited after this screen from the prior screen list.
If you use the [Help] key to display a help information screen, the help screen will not appear in the prior screen list.
Using the NEXT command does not update the prior screen list.
Help Key
Most NMMGR screens have a [Help] key as the second key from the right. Pressing this key displays a help information screen. The help information relates specifically to the screen from which you pressed the [Help] key. It describes screen usage, parameters, and function key operation for that screen. See "Getting Help" in this chapter for more information on the NMMGR Help system.Save Data Key
Screens with data entry fields have a [Save Data] key, usually as the third key from the right-hand side. Pressing this key creates or modifies the data record and causes the data entered in the screen to be transferred to the configuration file. If the Data Flag is "N", pressing [Save Data] will cause the Data Flag to change to "Y"."Go To" Keys
Some keys take you to a specific screen. There may be one or more keys on the screen that tell NMMGR to "go to" a new screen. For example, the [Go to OUTPUT] key on the Utility screen takes you directly to the Output Configuration File screen.Next Page/Prev Page Keys
Some NMMGR screens contain data or display sets of items that will not fit in a single screen. When this occurs, the screen data is continued on one or more "pages". The screens will include function keys that allow you to move back and forth between the pages of the screen. [Next Page] moves you to the subsequent page of data. [Prev Page] moves you to the prior page of data. Some multiple page screens also include [First Page] and [Last Page] keys, that take you to the first or last page of the data.Refreshing the Screen
If you have entered data or changed values on a data screen and decide not to make the changes before you have entered them into the configuration file, you can refresh the screen to return it to the state it was in before you made the changes. Simply enter REFRESH (or the abbreviation R) in the command window and press [ENTER]. NMMGR will warn you that the screen has changed since you last updated it. Enter REFRESH again; NMMGR refreshes the screen and shows its current configuration file data. In addition, refreshing the screen resets the terminal strap settings. You can also use the REFRESH command to "clean up" the screen after a "TELL" message or other interference has appeared on the screen.
