Common Screen Elements
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
This line is a full-bright inverse video line that is used only for
displaying information. You can obtain more information about the
errors that may appear in this field by using the Error Information
screen, which is described later in this chapter.
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. You can enter each command
using the full command name or you can abbreviate the command by
