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.
STATNAM NTKEY FIND NTALT BROWSE NTALT GET NTALT ACCEPT NTALT REJECT NTALT HISTOGRAM
STATNAM NTKEY FIND NTSYN RECHERCHE NTALT BROWSE NTSYN LISEZ NTALT % NTALT ACCEPT NTALT REJECT NTALT % |
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 SPACE *--------------------------------------------------------------- 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.
