Invoking or Closing the Natural Main Menu

There are two methods of invoking or closing the Natural Main Menu:

You can define a default setting by switching menu mode on or off. Menu mode causes the Natural Main Menu to be invoked automatically for the next session started.
You can invoke or close the Natural Main Menu within a Natural session whenever required.

To switch menu mode on or off before session start

At Natural startup, specify either of the following profile parameters:
```
MENU=ON
```
(activates menu mode)

or
```
MENU=OFF
```
(deactivates menu mode)

See also MENU in the Parameter Reference documentation.

To invoke or close the Natural Main Menu within a session

Enter either of the following system commands:
```
MAINMENU
```
(invokes the menu)

or
```
MAINMENU OFF
```
(closes the menu)
Choose ENTER.

The Natural Main Menu looks similar to the example shown below:

At session start, Natural assigns you to a default library that is indicated on the screen. In the example screen above, the ID (name) of the library is shown in the Library field in the top right-hand corner of the screen. See also Default Library Assignment.

For instructions on performing a menu function, refer to the relevant section in Using Commands and Menu Functions.

Each function listed in the Natural Main Menu invokes a menu of the corresponding name where you can select further functions:

Function in Natural Main Menu	Explanation of Functions in Corresponding Menu
Development Functions	Creates and maintains programs, maps, data areas and other components that make up a Natural application.
Development Environment Settings	Displays and modifies various settings that affect your Natural session.
Maintenance and Transfer Utilities	Invokes a Natural utility to create and maintain certain objects or transfer them to another environment.
Debugging and Monitoring Utilities	Invokes a Natural utility to monitor your Natural applications and locate errors in their processing flow.

Note:
The position and color of the message line and PF-key lines in the Natural Main Menu and its subordinate menus can be changed with the user exit routine USR2003P described in the Operations documentation.

Development Functions

The functions listed in the Development Functions menu are those you will need most frequently when you develop an application with Natural. The functions apply to all Natural objects that are available in the library where you are currently logged on.

The table below contains information on the fields provided in the Development Functions menu:

Field	Explanation
User	The ID of the Natural user who logged in the current session.
Library	The library currently active. See also the section Using Natural Libraries.
Mode	The programming mode: reporting or structured mode. See Programming Modes.
Work area empty	Indicates that no source has been loaded into the source work area. If a source has already been loaded into the source work area, the type and the name of the object will be displayed instead, for example, `Program PROGX`.
Code	The code that corresponds to the function required, for example, C for Create Object. See also Performing a Menu Function.
Type	The type of object such as `P` for program. For details, see Object Types in the Programming Guide. You can leave the Type field blank if you specify the name of a Natural object that already exists. If you want to change the object type, see also Setting the Object Type.
Name	The name of the object. For an explanation of valid object names, see Object Naming Conventions.
Command ===>	The command line. It is an input field in which you can enter a Natural command. For example: To edit an existing program named PROGX, you would enter the following system command: `EDIT PROGX` See also Using Commands and Menu Functions.
PF (function keys)	PF keys (function keys) can be used as an alternative to using commands or menu functions. The PF-key lines at the bottom of the screen indicate which function is assigned to which key. See also Standard PF Keys.

The table below contains information on the functions provided in the Development Functions menu. For most of the menu functions, there are equivalent Natural system commands. These alternative system commands are listed in the table and further explained in the relevant sections in the System Commands documentation.

Function	Code	Explanation
Create Object	`C`	Invokes a Natural editor where you can create a new object such as a program, map or data area. Specify the type and the name of the object to be created. You can enter a question mark (?) in the Type field, to select an object type from a list of all types available for this function. See also Creating and Editing Objects.
Edit Object	`E`	Invokes a Natural editor and displays the source of the specified object in modify mode. Specify the name of an existing object to be edited. You can also invoke a selection list of objects: see Specifying Object Ranges. You can enter a question mark (?) in the Type field, to select an object type from a list of all types available for this function. See also Creating and Editing Objects. Equivalent system command: `EDIT`
Rename Object	`R`	Invokes the Rename Objects window where you change the name of the specified object and/or the object type. See also Renaming Objects. Equivalent system command: `RENAME`
Delete Object	`D`	Invokes the Delete window for the specified object. In the Delete window, confirm the deletion by entering the name of the object again in the relevant input field. You can also invoke a selection list of objects as described in Specifying Object Ranges. In this list, you can mark one or more objects for deletion. See also Deleting Objects. Equivalent system command: `DELETE`
Execute Program	`X`	Executes an object of the type program. Specify the name of the object to be executed. Other object types cannot be executed by themselves, but must be invoked from another object. See also Executing Programs. Equivalent system command: `EXECUTE`
List Object(s)	`L`	Displays the source code of the specified object. Specify the name of the object to be displayed. You can also invoke a selection list of objects: see Specifying Object Ranges. You can enter a question mark (?) in the Type field, to select an object type from a list of all types available for this function. See also Listing Objects in a Library. Equivalent system command: `LIST`
List Subroutines Used	`S`	Ascertains which objects use which external subroutines and classes. Equivalent system command: `ROUTINES`

This section covers the following topics:

Programming Modes
Natural Editors
Specifying Object Ranges

Programming Modes

Natural offers two programming modes: reporting mode and structured mode. We recommend that you exclusively use structured mode, because it provides for more clearly structured applications. Therefore, all explanations and examples in the Natural tutorial First Steps and the Editors documentation refer to structured mode. Any peculiarities of reporting mode will not be taken into consideration.

For further information on programming modes, see the section Natural Programming Modes in the Programming Guide.

The Mode field in the top right-hand corner of the Development Functions menu indicates the programming mode currently in effect: structured or reporting.

To switch programming modes

In the upper right-hand corner of the Development Functions screen, in the Mode field, overwrite the first position with an S to switch on structured mode, or an R to switch on reporting mode.

Or:
Enter either of the following system commands:
```
GLOBALS SM=ON
```
(switches on structured mode)

or
```
GLOBALS SM=OFF
```
(switches on reporting mode)
Choose ENTER.

The contents of the Mode field has changed from Reporting to Structured or vice versa.

Natural Editors

Depending on the type of object specified in the Development Functions menu, Natural invokes the appropriate editor: the program editor, the map editor or the data area editor. For further information on these editors, see the relevant sections in the Editors documentation.

Specifying Object Ranges

The functions Edit Object, List Object(s) and Delete Object provide the option to either specify the name of an individual object or a range of names. When you specify a range of names, a list of objects is displayed from which you can select one or more objects you wish to edit or list, or mark for deletion.

To list all objects

In the Name field, enter an asterisk:
```
*
```
Choose ENTER.

A list of all objects available in the current library is displayed.

To list objects using a start value

In the Name field, enter a start value followed by an asterisk (*).

This option to enter a value followed by an asterisk is referred to as asterisk notation.

For example:
```
AB*
```
Choose ENTER.

A list of all objects with names that start with AB (for example, AB, AB1, ABC, ABEZ) is displayed for the current library. The list does not include object names that start with AA1 or ACB, for example.

Note:
The List Object(s) function provides further options to specify object name ranges as described for the equivalent system command LIST.

Development Environment Settings

The table below contains brief descriptions of the functions provided in the Development Environment Settings menu, and lists the Natural system commands that correspond to these functions.
