This document provides options to define a general screen layout:
With the terminal command %Y you can define
how and where the Natural function-key lines are to be displayed.
Below is information on:
The following terminal commands are available for defining the format of function-key lines:
- %YN
The function-key lines are displayed in tabular Software AG format:
Command ===> Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Help Exit Canc- %YS
The function-key lines display the keys sequentially and only show those keys to which names have been assigned (PF1=value, PF2=value, etc.):
- %YP
The function-key lines are displayed in PC-like format, that is, sequentially and only showing those keys to which names have been assigned (F1=value, F2=value, etc.):
Various other command options are available for function-key lines, such as:
single- and double-line display,
intensified display,
reverse video display,
color display.
For details on these options, see %Y - Control of PF-Key Lines in the Terminal Commands documentation.
- %YB
The function-key lines are displayed at the bottom of the screen.

- %YC
This command makes the function-key lines cursor-sensitive. This means that they act like an action bar on a PC screen: you just move the cursor to the desired function-key number or name and press Enter, and Natural reacts as if the corresponding function key had been pressed.
To switch cursor-sensitivity off, you enter
%YCagain (toggle switch).By using
%YCin conjunction with tabular display format (%YN) and having only the function-key names displayed (%YH), you can equip your applications with very comfortable action bar processing: the user merely has to select a function name with the cursor and press Enter, and the function is executed.
Various options of the terminal command %M are available
for defining how and where the Natural message line is to be displayed.
Below is information on:
- %MB
The message line is displayed at the bottom of the screen.

Other options for the positioning of the message line are described in %M - Control of Message Line in the Terminal Commands documentation.
- %MP
The message line is switched from unprotected to protected mode or vice versa. In unprotected mode, the message line can also be used for terminal input.
- %M=color-code
The message line is displayed in the specified color (for an explanation of color codes, see the session parameter
CDas described in the Parameter Reference).
You can use the terminal command %= to assign
colors to field attributes for programs that were originally not written for
color support. The command causes all fields/text defined with the specified
attributes to be displayed in the specified color.
If predefined color assignments are not suitable for your terminal type, you can use this command to override the original assignments with new ones.
You can also use the %= terminal command
within Natural editors, for example to define color assignments dynamically
during map creation.
| Codes | Description |
|---|---|
| blank | Clear color translate table. |
| F | Newly defined colors are to override colors assigned by the program. |
| N | Color attributes assigned by program are not to be modified. |
| O | Output field. |
| M | Modifiable field (output and input). |
| T | Text constant. |
| B | Blinking |
| C | Italic |
| D | Default |
| I | Intensified |
| U | Underlined |
| V | Reverse video |
| BG | Background |
| BL | Blue |
| GR | Green |
| NE | Neutral |
| PI | Pink |
| RE | Red |
| TU | Turquoise |
| YE | Yellow |
Example:
%=TI=RE,OB=YE
This example assigns the color red to all intensified text fields and yellow to all blinking output fields.
Outlining (boxing) is the capability to generate a line around certain fields when they are displayed on the terminal screen. Drawing such "boxes" around fields is another method of showing the user the lengths of fields and their positions on the screen.
Outlining is only available on certain types of terminals, usually those which also support the display of double-byte character sets.
The terminal command %D=B is used to
control outlining. For details on this command, see the relevant section in the
Terminal Commands documentation.
The terminal command %X controls the display of the Natural statistics line/infoline. The line can be used either as a statistics line or as an infoline, but not both at the same time.
Below is information on:
To turn the statistics line on/off, enter the terminal command
%X (this
is a toggle function). If you set the statistics line on, you can see
statistical information, such as:
the number of bytes transmitted to the screen during the previous screen operation,
the logical line size of the current page,
the physical line size of the window.
For full details regarding the statistics line, see the terminal
command %X as described in
the Terminal Commands documentation.
The example below shows the statistics line displayed at the bottom of the screen:
> > + Program POS Lib SAG
All ....+....1....+....2....+....3....+....4....+....5....+....6....+....7..
0010 SET CONTROL 'XB'

|
You can also use the statistics line as an infoline where status information can be displayed, for example, for debugging purposes, or you can use it as a separator line (as defined by SAA standards).
To define the statistics line as an infoline, you use the terminal
command %XI+.
Once you have activated the infoline with the above command, you can
define the infoline as the output destination for data with the
DEFINE PRINTER
statement as demonstrated in the example below:
SET CONTROL 'XT' SET CONTROL 'XI+' DEFINE PRINTER (2) OUTPUT 'INFOLINE' WRITE (2) 'EXECUTING' *PROGRAM 'BY' *INIT-USER WRITE 'TEST OUTPUT' END
When the above program is run, the status information is displayed in the infoline at the top of the output display:
EXECUTING POS BY SAG
Page 1 2001-01-22 10:56:06
TEST OUTPUT
|
For further details on the statistics line/infoline, see the terminal
command %X as described in
the Terminal Commands documentation.
Below is information on:
A window is that segment of a logical page, built by a program, which is displayed on the terminal screen.
A logical page is the output area for Natural; in other words the logical page contains the current report/map produced by the Natural program for display. This logical page may be larger than the physical screen.
There is always a window present, although you may not be aware of its
existence. Unless specified differently (by a
DEFINE WINDOW
statement), the size of the window is identical to the physical size of your
terminal screen.
You can manipulate a window in two ways:
You can control the size and position of the window on the physical screen.
You can control the position of the window on the logical page.
The figure below illustrates the positioning of a window on the physical screen. Note that the same section of the logical page is displayed in both cases, only the position of the window on the screen has changed.
The figure below illustrates the positioning of a window on the logical page.
When you change the position of the window on the logical page, the size and position of the window on the physical screen will remain unchanged. In other words, the window is not moved over the page, but the page is moved "underneath" the window.
You use the DEFINE
WINDOW statement to specify the size, position and attributes
of a window on the physical screen.
A DEFINE WINDOW statement does not activate a window; this
is done with a SET
WINDOW statement or with the
WINDOW clause
of an INPUT
statement.
Various options are available with the
DEFINE WINDOW
statement. These are described below in the context of the following example.
It refers to Natural's default terminal type setting; see also
terminal command %T= and profile
parameter TTYPE).
The following program defines a window on the physical screen.
** Example 'WINDX01': DEFINE WINDOW

The window-name identifies the window. The name may be up to 32
characters long. For a window name, the same naming conventions apply as for
user-defined variables. Here the name is TEST.
The window size is set with the SIZE option. Here the
window is 5 lines high and 25 columns (positions) wide.
The position of the window is set by the
BASE option.
Here the top left-hand corner of the window is positioned on line 5, column
40.
With the TITLE
option, you can define a title that is to be displayed in the window frame (of
course, only if you have defined a frame for the window).
With the CONTROL clause, you
determine whether the PF-key lines, the message line and the statistics line
are displayed in the window or on the full physical screen. Here CONTROL
WINDOW causes the message line to be displayed inside the window.
CONTROL SCREEN would cause the lines to be displayed on the full
physical screen outside the window. If you omit the CONTROL
clause, CONTROL WINDOW applies by default.
With the FRAMED option, you
define that the window is to be framed. This frame is then cursor-sensitive.
Where applicable, you can page forward, backward, left or right within the
window by simply placing the cursor over the appropriate symbol (<, -, +, or
>; see POSITION
clause) and then pressing Enter. In other words, you are moving the
logical page underneath the window on the physical screen. If no
symbols are displayed, you can page backward and forward within the window by
placing the cursor in the top frame line (for backward positioning) or bottom
frame line (for forward positioning) and then pressing Enter.
With the POSITION clause of the
FRAMED
option, you define that information on the position of the window on the
logical page is to be displayed in the frame of the window. This applies only
if the logical page is larger than the window; if it is not, the
POSITION clause will be ignored. The position information
indicates in which directions the logical page extends above, below, to the
left and to the right of the current window.
If the POSITION clause is omitted, POSITION SYMBOL
TOP RIGHT applies by default.
POSITION
SYMBOL causes the position information to be displayed in
form of symbols: "More: < - + >". The information is
displayed in the top and/or bottom frame line.
TOP/BOTTOM determines whether the position
information is displayed in the top or bottom frame line.
LEFT/RIGHT determines whether the position
information is displayed in the left or right part of the frame line.
You can define which characters are to be used for the frame with the
terminal command %F=chv.
| c | The first character will be used for the four corners of the window frame. |
|---|---|
| h | The second character will be used for the horizontal frame lines. |
| v | The third character will be used for the vertical frame lines. |
Example:
%F=+-!
The above command makes the window frame look like this:
+------------------------+ ! ! ! ! ! ! ! ! +------------------------+
The INPUT
WINDOW statement activates the window defined in the
DEFINE WINDOW
statement. In the example, the window TEST is activated. Note that if you wish
to output data in a window (for example, with a WRITE statement), you use the
SET WINDOW
statement.
When the above program is run, the window is displayed with one input
field COMMAND. The session parameter
AD is used
to define that the value of the field is displayed
intensified and an
underscore is used as filler
character.

is displayed in the window.
To see the information that is further down on the logical page, you place the cursor in the bottom frame line on the plus (+) sign and press Enter.
The window is now moved downwards. Note that the text long data

You can, of course, open multiple windows. However, only one Natural window is active at any one time, that is, the most recent window. Any previous windows may still be visible on the screen, but are no longer active and are ignored by Natural. You may enter input only in the most recent window. If there is not enough space to enter input, the window size must be adjusted first.
When TEST2 is entered in the COMMAND field,
the program WINDX02 is executed.

Note that for the new window the message line is now displayed
on the full physical screen (at the top)
and not in the
window. This was defined by the
CONTROL
SCREEN clause in the WINDX02 program.
For further details on the statements
DEFINE WINDOW,
INPUT
WINDOW and SET
WINDOW, see the corresponding descriptions in the
Statements documentation.
A standard layout can be defined in the map editor. This layout guarantees a uniform appearance for all maps that reference it throughout the application.
When a map that references a standard layout is initialized, the standard layout becomes a fixed part of the map. This means that if this standard layout is modified, all affected maps must be re-cataloged before the changes take effect.
In contrast to a standard layout, a dynamic layout does not become a fixed part of a map that references it, rather it is executed at runtime.
This means that if you define the map layout as dynamic in the map editor, any modifications to the layout map are also carried out on all maps that reference it. The maps need not be re-cataloged.
For details on defining standard and dynamic map layouts, see Format in Map Editor in the Editors documentation.
Using Natural, you can create multilingual applications for international use.
Maps, helproutines, error messages, programs, subprograms and copycodes can be defined in up to 60 different languages (including languages with double-byte character sets).
Below is information on:
In Natural, each language has a language code (from 1 to 60).
The table below is an extract from the full table of language codes. For a
complete overview, refer to the description of the system variable
*LANGUAGE
in the System Variables documentation.
| Language Code | Language | Map Code in Object Names |
|---|---|---|
| 1 | English | 1 |
| 2 | German | 2 |
| 3 | French | 3 |
| 4 | Spanish | 4 |
| 5 | Italian | 5 |
| 6 | Dutch | 6 |
| 7 | Turkish | 7 |
| 8 | Danish | 8 |
| 9 | Norwegian | 9 |
| 10 | Albanian | A |
| 11 | Portuguese | B |
The language code (left column) is the code that is contained in the
system variable *LANGUAGE.
This code is used by Natural internally. It is the code you use to define the
user language (see Defining the User
Language below). The code you use to identify the language
of a Natural object is the map code in the right-hand column of the
table.
Example:
The language code for Portuguese is "11". The code you use when cataloging a Portuguese Natural object is "B".
For the full table of language codes, see the system variable
*LANGUAGE
as described in the System Variables documentation.
To define the language of a Natural object (map, helproutine, program, subprogram or copycode), you add the corresponding map code to the object name. Apart from the map code, the name of the object must be identical for all languages.
In the example below, a map has been created in English and in German. To identify the languages of the maps, the map code that corresponds to the respective language has been included in the map name.
DEMO1 = English map (map code 1)
DEMO2 = German map (map code 2)
Map codes are in the range 1-9, A-Z or a-y. The alphabetical map codes require special handling.
Normally, it is not possible to catalog an object with a lower-case letter in the name - all characters are automatically converted into capitals.
This is however necessary, if for example you wish to define an object
for Kanji (Japanese) which has the language code 59 and the map code
x.
To catalog such an object, you first set the correct language code
(here 59) using the terminal command %L=nn,
where nn is the language code.
You then catalog the object using the ampersand (&) character
instead of the actual map code in the object name. So to have a Japanese
version of the map DEMO, you stow the map under the name
DEMO&.
If you now look at the list of Natural objects, you will see that the
map is correctly listed as DEMOx.
Objects with language codes 1-9 and upper case A-Z can be cataloged directly without the use of the ampersand (&) notation.
In the example list below, you can see the three maps
DEMO1, DEMO2 and DEMOx. To delete the
map DEMOx, you use the same method as when creating it, that is,
you set the correct language with the terminal command
%L=59 and
then confirm the deletion with the ampersand (&) notation
(DEMO&).

You define the language to be used per user - as defined in the system
variable *LANGUAGE
- with the profile parameter ULANG (which is
described in the Parameter Reference) or with the terminal
command %L=nn
(where nn is the language code).
To reference multilingual objects in a program, you use the ampersand (&) character in the name of the object.
The program below uses the maps DEMO1 and
DEMO2. The ampersand (&) character at the end of the map name
stands for the map code and indicates that the map with the current language as
defined in the *LANGUAGE system variable is to be
used.

For some applications it may be useful to define multilingual programs. For example, a standard invoicing program, might use different subprograms to handle various tax aspects, depending on the country where the invoice is to be written.
Multilingual programs are defined with the same technique as described above for maps.
Using the Natural utility SYSERR, you can translate Natural error messages into up to 60 languages, and also define your own error messages.
Which message language a user sees, depends on the
*LANGUAGE
system variable.
For further information on error messages, see SYSERR Utility in the Utilities documentation.
The language used for date and time fields defined with edit masks also
depends on the system variable *LANGUAGE.
For details on edit masks, see the session parameter
EM as
described in the Parameter Reference.
Users with varying levels of skill may wish to have different maps (of varying detail) while using the same application.
If your application is not for international use by users speaking different languages, you can use the techniques for multilingual maps to define maps of varying detail.
For example, you could define language code 1 as corresponding to the skill of the beginner, and language code 2 as corresponding to the skill of the advanced user. This simple but effective technique is illustrated below.
The following map (PERS1) includes instructions for the end user on how to select a function from the menu. The information is very detailed. The name of the map contains the map code 1:
