This document describes the Natural text modules NATTEXT,
NATTXT2 and NATTXT3. It covers the following
topics:
All Natural keywords, alternative keywords and standard output text are
contained in the modules NATTEXT and
NATTXT2. Natural
system commands and alternate system commands are also included as keywords and
alternative keywords in these modules. Substitution text fragments for Natural
error messages are contained in module NATTXT3. The modules are
contained in source form in the Natural source library and in load module form
in the Natural load library.
If necessary, you can modify Natural keywords, alternative keywords and text contained in these modules. For example, Natural session termination messages can be changed from English to another language, Natural keywords can be disabled, or synonyms can be added.
If any modifications are made to a NATTEXT,
NATTXT2 or NATTXT3 module, each modified module must
be assembled, link-edited and included into the executable Natural module,
refer to the Natural Installation
documentation.
The NATTEXT module contains NTKEY and
NTALT macros for each keyword and alternative keyword to be
recognized by Natural.
 |
Warning: It is recommended that you modify the NATTEXT module
for very important reasons only, because once modified, it can no longer be
properly maintained by Software AG personnel. |
The following rules apply:
A keyword value for a NTKEY or
NTALT macro can be changed by replacing the current
keyword value with the desired value.
A keyword or alternative keyword can be disabled by replacing the keyword value with the character "%".
The position of each NTKEY and
NTALT macro within the module is fixed and must not be
shifted. Additional NTKEY and
NTALT macros must not be inserted.
Synonyms can be assigned for any keyword or alternative keyword using
the NTSYN macro. One or more
NTSYN macros can be inserted after a
NTKEY or NTALT macro. The
NTSYN macro includes one parameter, which is the value
to be used as the synonym. If the synonym contains embedded blanks, the entire
value must be enclosed in apostrophes.
The following example illustrates how a NATTEXT module is
modified. In this example
the synonym RECHERCHE is to be used for the keyword
FIND;
the synonym LISEZ is to be used for the alternative
keyword BROWSE;
the keywords GET and HISTOGRAM are to be
disabled.

The NATTXT2 module contains the macros
NTKEYT, NTALTT,
NTSYNT and NTERMSG which define
the following:
The module NATTXT2 contains the following standard Natural
output texts, each of which can also be displayed in another language if the
language code is set accordingly (see also below):
the literal Page used in the standard output page
header;
the name of each month as used in the Natural system variable
*DATG (Gregorian date), date edit masks (L), and
the name of each day as used in date edit masks (N);
the ENTER INPUT DATA message and the skeleton error
messages for error numbers 1104, 1105 and 1106 (used during online input
processing);
the error message used for system file open failure (which cannot be
retrieved from the system file); an error number of the form
NAT8xxx (where
xxx is the decimal Adabas response code) is added to
this error message by Natural;
the constants More, Top and
Bottom used in windows for position information to be displayed in
text form;
the table to define reports and report handling for reports greater than 33.
Any values contained in NATTXT2 can be modified by
replacing the current text with the desired text. If a month-name synonym
exceeds nine characters, only the first nine positions are used by the system
variable *DATG.
NTSYNT macro statements can be added as
described for module NATTEXT. However, with NATTXT2,
a second parameter can be specified. This parameter is optional and represents
the language indicator to be used for the synonym. When you specify the
language indicator, Natural produces message output resulting from the use of
this synonym in the corresponding language. In addition, if error message texts
have been stored in the Natural system file using a language indicator other
than 1 (which is the default and stands for English),
error messages are returned in the corresponding language. For information on
which language code stands for which language, refer to the profile parameter
ULANG.
The module NATTXT2 contains NTKEYT
and NTALTT macros for each keyword and alternative
keyword to be recognized by Natural for the following Natural system commands
and utilities, parameters of commands and their values when applicable. Each of
these can also be used in another language if the language code is set
accordingly (see also below):
all Natural system commands in general;
for the GLOBALS
system command, the parameters and their values when applicable;
for the COMPOPT
system command, the parameters and their values when applicable;
public system commands (these system commands are permanently valid
and cannot be disallowed neither by means of
Natural Security nor by the
Natural profile parameter NC;
Natural utilities
The NTKEYT and NTALTT
macro statements can be used similar to the NTKEY and
NTALT macro statements as described for module
NATTEXT.
The NTSYNT macro statements can be used as described under
Standard Natural
Output Texts.
Natural has a number of standard session termination messages
(NAT99...) that are delivered in macro NTERMSG and can be modified
there (for example, to translate them it into another language). The overall
length of ID and text can be up to 72 characters. After the macro
NTERMSG has been modified, the Natural parameter module and if
supplied in source code, the environment dependant driver have to be
re-assembled and linked.
Apart from the message ID and text, each standard termination message
also includes one of the following Natural system return codes, which are also
defined within macro NTERMSG:
| Code | Explanation |
|---|---|
0 |
Normal termination. |
4 |
Error occurred during execution/compilation (batch mode only). |
8 |
Termination due to severe runtime error. |
12 |
Session initialization failure. |
16 |
Abnormal termination due to abend or severe environment failure.. |
User-written termination messages can be added to NATXT2
for all return codes (1 - 255) which can be issued with a
TERMINATE statement
and which normally lead to the Natural termination message NAT9987.
For user-written termination messages, the corresponding return code must be specified as the second parameter.
With the profile parameter TS set to
ON, the termination messages are translated to upper case using
the upper case translation table
NTUTAB1
as supplied in the
NATCONFG
module before they are displayed.
In addition to TS=ON, further parameters to provide for
translation of messages into upper case are provided by several Natural
components. For further information, see
Other Parameters to
Provide Upper Case Translation in the
TS profile
parameter description.
Example of a User Termination Message:
NTERMSG 'USR0077 THIS IS A SAMPLE USER MESSAGE FOR RETURN CODE 77',77
The NATTXT3 module contains the macros to define the text
fragments which will be used to substitute the :n:
place holder in Natural error messages.
Each text fragment can be defined in various languages. For information
on which language code stands for which language, refer to the
ULANG
parameter.
The text fragments will be generated in EBCDIC and Unicode notation.
Note:
To assemble the NATTXT3 module, a high level assembler
must be used which supports the macro function UPPER and the
definition of unicode characters (DC CU’unicode
text’).
Example:
The text for Natural error NAT0082 (when trying to execute a non existing program) looks as follows:
Invalid command, or :1: :2: does not exist in library.
Trying to execute the object NOTEXIST leads to following
result:
NAT0082 Invalid command, or Program NOTEXIST does not exist in library.
:2: was replaced by the object name
(NOTEXIST).
:1: was replaced by the text fragment
Program.
The text fragment was declared in module NATTXT3 as
follows:
*===============================================================
* PROGRAM 0002
*===============================================================

Text fragment values for additional languages may be entered by adding
further MSGSLAN macros.
