This document describes the Natural text modules NATTEXT,
NATTXT2, NATTXT2U, NATTXT3 and the
Natural macro NTERMSG.
NATTXT2 - Output Text, Keywords and User Termination Messages (Mixed Case)
NATTXT2U - Output Text, Keywords and User Termination Messages (Uppercase)
NATTXT3 - Text Fragments for Placeholders in Natural Error Messages
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 corresponding Natural installation documentation.
The NATTEXT module contains the macros
NTKEY, NTALT and NTSYN 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 and
NTSYNT 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.
User-written termination messages can be added with the macro
NTERMSG for all return codes (1 - 255) which can be
issued with a TERMINATE statement and which
normally lead to the Natural termination message NAT9987.
You specify the termination message text with the first parameter, and the corresponding return code with the second parameter.
NTERMSG 'USR0077 THIS IS A SAMPLE USER MESSAGE FOR RETURN CODE 77',77
A TERMINATE 77 statement in a Natural application
will result in the following termination message: USR0077 THIS IS A
SAMPLE USER MESSAGE FOR RETURN CODE 77.
The NATTXT2U module contains the same items as the
NATTXT2 module. The difference is that certain keywords for the
English language are contained in mixed case in NATTXT2 whereas
they are in all uppercase in NATTXT2U. This affects the keywords
MORE, TOP, BOTTOM, PAGE,
and all month and weekday names.
NATTXT2U should be linked to the Natural nucleus
instead of NATTXT2 in environments where lower-case code points
H'81' to H'A9' are used to display national
characters, for example, if code page 930 with half-width Katakana characters
is used.
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
*===============================================================
MSGSDEF &LC_PGM

*---------------------------------------------------------------
MSGSLAN 01,Program 1 ENGLISH
MSGSLAN 02,Programm 2 GERMAN
MSGSLAN 03,programme 3 FRENCH
MSGSLAN 04,programa 4 SPANISH
SPACE

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