# Configuring your Natural Environment

Natural parameters manage the configuration of a Natural environment.

Natural parameters are used to standardize and automate development and production processes or adapt standard settings to the needs of individual users. A Natural parameter, for example, is used to set defaults for report creation, define the size of a report or define the size of storage area required such as the source area of an editor.

Most of the characteristics of a Natural environment are predefined by the product. The Natural administrator can configure different default environment settings valid for all Natural users. A user can adapt the settings to his needs by overriding default environment settings with a dynamic profile parameter or session parameter.

This section covers the following topics:

- Using Profile Parameters

- Using Session Parameters

- Parameterization Levels

## Using Profile Parameters

Profile parameters are specified statically or dynamically.

Static parameters are specified in the Natural parameter module, during the installation of Natural. They are used as the default for each Natural session.

Dynamic parameters are specified at the start of a Natural session. You can predefine a set of dynamic parameters with the Natural SYSPARM utility.

A predefined set of dynamic parameters is a Natural object of the type parameter profile.

At session start, you can specify one or more parameter profiles and one or more single profile parameters as indicated in To specify profile parameters at session start.

A parameter specified at session start (with a parameter profile or without), overrides any value specified for the corresponding parameter in a standard parameter profile assigned to a session and/or in the Natural parameter module; see also Parameterization Levels.

To set profile parameters in the Natural parameter module

- Follow the instructions provided in Building a Natural Parameter Module in the Operations documentation.

To create a parameter profile using SYSPARM

1. Invoke the SYSPARM utility by entering the following system command:

       SYSPARM

2. Press ENTER.

   The Menu of the Natural SYSPARM utility appears.

3. In the Code field, enter an `A` (Add New Profile), and in the Profile field, enter the name of the parameter profile you want to create as shown in the example below:

6. Press PF4 (Check) to check and, if required, correct the syntax.

   For the syntax that applies, refer to Dynamic Assignment of Parameter Values in the Operations documentation.

7. Press PF5 (Save) to save the parameter profile as a source object under the specified name in the current system file (the default setting is FNAT).

To set profile parameters at session start

- Enter one or more parameter profiles (if available) and/or one or more profile parameters. Parameter profiles and profile parameters can be entered in any order. However, if a parameter is specified more than once (in the example below: `FUSER`), the value assigned to this parameter in the last specification is used (in the example below: `10,245`).

      PROFILE=TESTPROF FUSER=(10,123) DSIZE=40 LS=250,PS=50 FUSER=(10,245)

## Using Session Parameters

Session parameters are specified within an active Natural session and/or within a Natural object. The main purpose of session parameters is to control the execution of Natural programs.

To set a session parameter

- Follow the instructions provided in How to Set Session Parameters in the Parameter Reference documentation.

To check or modify parameter settings for the current session

- Choose either of the following methods:

  1. Enter the following system command:

         GLOBALS

     Press ENTER.

     A Session Parameters screen similar to the example below appears which displays the current settings of session parameters:

         10:28:03              ***** NATURAL GLOBALS COMMAND *****            2009-05-20

         Command ===>

         Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12---
               Help  Print Exit        Updat                                     Canc

     The letters in parentheses indicate the session parameter; see also List of Parameters in GLOBALS in the System Commands documentation.

     You can change the setting of a parameter by replacing the default value entered next to the parameter required. For valid input values, refer to the relevant description of the session parameter in the section Session Parameters in the Parameter Reference documentation.

     For example:

     To change the setting of the date format parameter `DFOUT`, overwrite the value next to the input field of (DFOUT) Date Format Output (in the example above `S`) by an `I`.

     Press PF5 (Updat) to save the modification.

     The format of date variables changes from yy-mm-dd (for example: `2009-06-16`) to yyymmdd (for example: `20090616`).

  2. Enter the following system command:

         GLOBALS parameter=value

     where:

     parameter is the session parameter (in the example below: `DFOUT`).

     value is a valid value for this session parameter (in the example below: `I`).

     You can specify multiple parameters and values.

     For example:

         GLOBALS DFOUT=I PS=60

     Press ENTER.

## Parameterization Levels

There is a hierarchical structure of the levels at which Natural parameters can be set. A parameter value set on a higher level overrides the value defined on a lower level. For example, when you specify a parameter dynamically, the new parameter value overrides the static specification as set for the corresponding parameter in the Natural parameter module.

The diagram below illustrates when a parameter can be set and the Natural parameter hierarchy from the lowest level at the base of the pyramid to the highest level at the apex:
