Facility
NonStop NET/MASTER MS provides an extensive help facility. By default, the F1 (PF01) function key is the HELP function key, which is used to access online help. Three types of help are available:
Help for a service, facility, or panel Help for a message
Help for a command
Help for a Service, Facility, or Panel
To display help text describing the function of a particular service, facility, or panel, press the HELP function key from a panel that indicates help information is available. For example, if you press the HELP function key from the Edit Services Selection List panel, several pages of information describing the Edit Services facility are displayed. You can scroll forward and backward through the help panels by pressing the F8 (PF08) and F7 (PF07) function keys, respectively. To exit from the help facility, press the F3 (PF03) function key.
See later sections in this manual, and refer to the NonStop NET/MASTER MS System
Management Guide, for more information about services, facilities, and panels. Help for a Message NonStop NET/MASTER MS displays many messages, which report events, indicate
the results of a command, and so on. There are two methods you can use to obtain online help about a message displayed on the screen. The following table displays the locations from which you can use each method:
Method OCS Command Entry Activity Log
1 Yes Yes Yes
2 Yes Yes No
Method 1 is to position the cursor on a line on which the message is displayed (next to the message number) and press the HELP function key. Method 2 is to type the message number in the OCS command input line or the Command Entry facility COMMAND field, and to press the HELP function key.
The panel that appears depends on the message about which you are obtaining help. If the message begins with NNM, it is a NonStop NET/MASTER MS message. Help information about the message is in the NonStop NET/MASTER MS message help database (and also in the NonStop NET/MASTER Messages Manual).
If NonStop NET/MASTER MS recognizes a message beginning with NNM, the Browse NonStop NET/MASTER Messages panel appears with detailed help
information for the message: otherwise, NonStop NET/MASTER MS displays help for the next sequential message.
Using the NonStop NET/MASTER MS Help Facility
If the message begins with characters other than NNM, the message is not a NonStop NET/MASTER MS message. Rather, the message is from a Tandem or user-written subsystem, sent to NonStop NET/MASTER MS from an EMS distributor. Help information about the message is in the event detail database, in either the EVENTTD or EVENTCX file (see the NonStop NET/MASTER MS System Management Guide for more information about these files).
Note If the NonStop NET/MASTER MS Event Detail Help panel displays F10=PrevMsg and F11=NextMsg on the bottom line, the information is from the EVENTCX file: otherwise, the information is from the EVENTTD file.
If NonStop NET/MASTER MS recognizes a message beginning with other than NNM, the NonStop NET/MASTER MS Event Detail Help panel appears with detailed help information for the message: otherwise, NonStop NET/MASTER MS displays message NNM0976 to indicate that no help is available.
Table 1-1 shows the function keys used to scroll through messages in the NonStop NET/MASTER MS message help database, the EVENTTD file, and the EVENTCX file. Press the F3 (PF03) or F4 (PF04) function key to return to the location from which you requested help.

Customized Message Help Information
A programmer or system manager can customize message help information. Refer to the NonStop NET/MASTER MS System Management Guide for more information.
Help for a Command You can use many commands from NonStop NET/MASTER MS. There are four methods you can use to obtain online help about a NonStop NET/MASTER MS command. The following table displays the locations from which you can use each method:
Method OCS Command Entry Activity Log
1 Yes Yes Yes
2 Yes Yes No
3 Yes Yes No
4 Yes No No
Method 1 is to position the cursor on a line on which the command is displayed (next to the command) and press the HELP function key. Method 2 is to type the name of a command in the OCS command input line or the Command Entry facility
COMMAND field, and to press the HELP function key.
For both Method 1 and Method 2, if NonStop NET/MASTER MS recognizes the command, detailed help information for the command is displayed. Press the F3 (PF03) or F4 (PF04) function key to return to the location from which you requested help.
For both Method 1 and Method 2, if NonStop NET/MASTER MS does not recognize the command (perhaps you mistyped the command or the command was ambiguous), NonStop NET/MASTER MS displays the NonStop NET/MASTER Command Tutorial Selection List panel. See “Scrolling Through the Command Tutorial Selection List,” later in this section, for how to continue.
Method 3 is to type HELP in the OCS command input line or the Command Entry facility COMMAND field, and to press the ENTER key. Method 4 is to leave the OCS command input line blank and press the HELP function key.
For both Method 3 and Method 4, the NonStop NET/MASTER Command Tutorial panel appears. To continue, do one of the following:
Press the ENTER key.
The NonStop NET/MASTER Command Tutorial Selection List panel appears. See “Scrolling Through the Command Tutorial Selection List,” later in this section, for how to continue.

Refer to the NonStop NET/MASTER MS Command Reference Manual for detailed information about commands.
Scrolling Through the Command Tutorial Selection List
The Command Tutorial Selection List is a list of NonStop NET/MASTER MS and SOLVE management services commands. When the selection list appears, the cursor is positioned next to the command that is alphabetically the closest to the string you typed.
To scroll through the Command Tutorial Selection List, enter a value in the Scroll field to control the amount of scrolling. Then press the F7 (PF07) or F8 (PF08) function key to determine the type of scrolling (backward or forward), as described in Table 1-2. This table also lists the values that you can enter in the Scroll field.

The Function Keys
The function keys on your keyboard are assigned default definitions (listed in Table 1-3), which are generally consistent throughout NonStop NET/MASTER MS. In addition, each NonStop NET/MASTER MS facility has its own specialized function key definitions, which are described in the appropriate sections throughout the rest of this manual.Table 1-3. Default Function Key Definitions
6530 Function Key 3270 Function Key Description
F1 PF01 Displays help.
F2 PF02 Executes the NonStop NET/MASTER MS SPLIT
command to open a new window.
F3 PF03 Executes the NonStop NET/MASTER MS X
command to return to the screen from which the current screen was invoked.
(Note: in some panels, the F3 (PF03) key is used to update information.)
F4 PF04 Executes the NonStop NET/MASTER MS RETURN
command to return to the menu from which the current screen was invoked.
F9 PF09 Executes the NonStop NET/MASTER MS SWAP
