This system variable indicates that the application is running in a web
browser. An application can run in a web browser either via the
Natural Web I/O
Interface or by using
Natural for
Ajax. An application that is running with the Natural Web I/O
Interface can use maps. An application that is running with Natural for Ajax
can use both maps and rich GUI pages (using the
PROCESS PAGE
statement).
This system variable may contain one of the following values:
| Value | Description |
|---|---|
| (empty) | The application is not running in a web browser. |
| WEB | The application is running with the Natural Web I/O Interface.
It cannot use the PROCESS
PAGE statement.
|
| RICHGUI | The application is running with Natural for Ajax. It can use the
PROCESS PAGE
statement.

This system variable is applicable under Natural Security only. It contains the ID via which a user is logged on to a protected library, that is, the ID via which the user is linked to the library. This may be either the ID of the group via which the user is linked or the user's own ID (if he or she is linked directly).
*GROUP will be blank under the following
conditions:
in the case of a logon to an unprotected library (where no link is used),
if Natural Security is not active.

file used.

This system variable contains the language indicator (language code).
This language indicator is used for edit masks of date fields, Natural error
messages and user error messages as used in the statements
INPUT and
REINPUT.
A one-character code is assigned to each language code; this
one-character code is used to replace all ampersand characters (&) in names
of language-specific objects (for example, maps, dialogs, helproutines,
subprograms). For details on the use of the ampersand character in Natural
object names, see the descriptions of the statements
CALLNAT
(operand1),
FETCH
(operand1),
INCLUDE
(copycode-name) and
INPUT
(USING MAP) and the session parameter
HE
(operand1).
You can specify up to 60 different language codes. The codes are listed below.
The system variable *LANGUAGE is set by the
Natural profile parameter ULANG which
determines the language to be used for date edit masks, system messages, user
messages, help texts, help routines and multi-lingual maps.
Natural does not differentiate between compile time and
run time. It always tries to read the map with the current value of
*LANGUAGE first and if not found, it then tries to
find the map with the default language.
For details on how to use language codes, see also Multilingual User Interfaces in the Programming Guide.
The following languages are assigned to the individual language codes (the right-hand column shows the corresponding one-character codes to be used in names of language-specific objects):

This system variable indicates whether a screen I/O is possible or not.
It can contain one of the following values:
| TRUE | Screen I/O is possible. |
|---|---|
| FALSE | Screen I/O is not possible. |
In an interactive Natural session,
*SCREEN-IO is initialized with TRUE.
In a Natural batch session, *SCREEN-IO is
initialized with FALSE (except for a Natural Development Server).
If Natural was started as a DB2 Stored Procedures server (*SERVER-TYPE =
DB2-SP) or as RPC server (*SERVER-TYPE = RPC)
*SCREEN-IO is set to FALSE.
When *SCREEN-IO is set to
FALSE and a statement which requires user interaction is executed,
Natural issues error NAT0723.

| WEBIO | Natural Web I/O Interface server |
If Natural is not started as a server,
*SERVER-TYPE is set to blanks.

*SERVER-TYPE refers to Natural as a
whole, not to the Natural program currently being executed (which may
run as a client program or as a server program within a server Natural).
