Buffer Sizes

Natural uses several buffer areas for the storage of programs and data. You may need to adjust their sizes in order to achieve maximum buffer efficiency.

See also Buffer Pool Assignments in the local configuration file.

Character Assignments

The following profile parameters are used to change default character assignments.

Once a character has been defined to replace a default character, this character cannot be used as data.

Command Execution

The following profile parameters are used to control the execution of commands.

Date Representation

The following profile parameters are used to control the representation of dates.

Device/Report Assignments

These parameters are used to modify your screen and printer configurations as well as your report assignments.

See also the profile parameter CMPRTnn which is used for additional reports in batch mode.

Device Assignments

The Devices group shows a scrollable list of configurable logical devices (VIDEO and the logical printers LPT1 to LPT31) as used in the DEFINE PRINTER statement. The following information can be changed:

Method

The buttons in this column display the print method used for the corresponding print device. You can choose a button to toggle the print methods.

Print Method	Description
TTY	This is the raw printing method where the text output by the Natural program is essentially forwarded to the spooler in unaltered form. Any printer commands must either be output as data by the Natural program or statically defined in TTY printer profiles. The Windows printer driver is not used.
GUI	This is the preferred print method under Windows, whereby the output from the Natural program is passed through the Windows printer driver associated with the specified printer. Unlike the TTY method, no knowledge of printer commands is required, since these are automatically inserted by the printer driver.

Close mode

You can select a different close mode for each logical printer. Possible values in the drop-down list box are:

Close Mode	Description
Auto	Printers are automatically closed at the end of a program or when the execution of a called method is terminated. This is the default setting.
User	Closing of printers is controlled by the user. The printer is closed, if one of the following conditions is met: a CLOSE PRINTER statement is executed, a DEFINE PRINTER statement is executed, the session terminates.

The following program example describes the user-controlled closing of printers. Note that the close mode must be first set in the parameter file.

DEFINE DATA
  LOCAL
  1 #OUT (A8)
END-DEFINE
*
#OUT := *PROGRAM
*
* Write to report with close mode "user"
WRITE (1) 'OUTPUT PROGRAM: ' #OUT
*
* Write to report with close mode "auto"
WRITE (2) 'OUTPUT PROGRAM: ' #OUT
*
* Close printer 1
* Printer 1 is user-controlled
CLOSE PRINTER (1)
*
END

Line Size

See the description of the LS parameter.

Page Size

See the description of the PS parameter.

Max. Pages

See the description of the MP parameter.

Setup

You can choose a button in this column invoke a print method-specific dialog box:

Print Method	Description
TTY	When you choose the Setup button for this print method, the Setup TTY dialog box appears in which you can specify the following options: Physical specification This corresponds to the printer name. Instead of selecting an existing physical printer specification from the drop-down list box, you can also enter a file name if you want your output to be written to a file. Note: A server printer can be specified via the UNC naming convention (\\server-name\printer-name). Print to file Using this check box, you can specify whether file I/O is to be used to access the specified device (e.g. for printers which are set up as file system shares). If this check box is not selected, the data is output via spooler API function calls.
GUI	When you choose the Setup button for this print method, the standard Windows Print Setup dialog box appears and you can select the Windows printer and associated print options such as page size and orientation. Note: If you wish to make use of the default Windows printer on each client computer at run-time, this dialog should not be used. Alternatively, if a specific printer has already been chosen (even in a previous session) for this logical device, the default printer can be implicitly re-selected by switching the print method to TTY, closing the application, re-opening the application and switching the print method back to GUI. Note that any print options for the default printer must be set by using a printer profile.

Note:
The following applies to the print method TTY if the Print to file check box has been activated. As with work files, a file name can be defined by using environment variables. Any existing file of the same name at the specified location is normally overwritten, unless the entered file name is immediately prefixed by two right angle bracket characters (>>).

Report Assignments

The Reports group shows a scrollable list in which you can assign a Natural report number (report 1 to report 31) to a logical device name. The following information can be changed:

Device

For each report number, you can select another output medium. Possible values in the drop-down list box are:

Value	Description
LPT1 to LPT31	Outputs the report data to the corresponding physical device.
SOURCE	Outputs the report data to the source area. The user can then, for example, issue the EDIT command to open the output data in the editor and save it accordingly.
DUMMY	Report data are discarded.
INFOLINE	Report data are sent to the infoline. See also the description of the terminal command %X.

Report 0 is always implicitly assigned to VIDEO (that is, the output is shown on the screen). No other report number can be assigned to VIDEO.

Profile

In addition to the name of the logical device, you can assign a printer profile that has been defined in the Printer Profiles node of the global configuration file. All defined printer profiles can be selected from the drop-down list box. Select the blank entry if you do not want to use any of these profiles.

Important:
Any specified printer profile must match the print method used at run-time. For example, if an attempt is made to use a GUI printer profile for a TTY logical device (or vice versa), the printer profile specification is ignored.

Error Handling

The following profile parameters are used to control error handling within Natural.

Field Appearance

The following profile parameters influence I/O handling.

Limits

The following profile parameters are used to prevent a single program from consuming an excessive amount of internal resources.

Program Loading and Deletion

The following profile parameters are used to control the dynamic loading and deletion of programs.

Regional Settings

The following profile parameters are used to control the country- or region-specific settings of Natural.

Report Parameters

The following profile parameters are used to control various attributes of Natural reports.

Steplibs

The following parameters are used to manage the steplibs.

Additional Steplib Assignments

You can define up to eight libraries that can be searched for objects which cannot be found in the current library. These additional steplibs are defined in a table. The steplib number is shown in the first column. The following information can be specified:

Name

The name of an existing library.

DBID

The database ID of the file system where the library is located.

FNR

The file number of the file system where the library is located.

Note:
The following application programming interfaces are available for handling multiple steplibs: USR3025N (when Natural Security is not installed) and USR4025N (when Natural Security is installed).

System Files

The following profile parameters are used to specify the Natural system files. A page is provided for each parameter, on which you can specify DBID, FNR, path, read only access, password and cipher for each system file.

If you select a path that has already been assigned to another system file, all relevant internal information of the first assignment is copied automatically to the new assignment.

The physical location of each system file is defined in the global configuration file. See System Files in the global configuration file.

System Variables

The following profile parameters are used to adjust Natural system variables for the start of a Natural session.

See also the System Variables documentation.

Note:
You can use the command line parameters NATVERS (to specify the Natural version) and PARM (to specify a specific Natural parameter file) at session startup. These parameters can only be specified dynamically, therefore, they cannot be modified or viewed within the Configuration Utility.

Work Files

The following profile parameters can be used to specify work file settings.

See also the profile parameter CMWRKnn which applies to batch mode.

See also Work Files in the Operations documentation.

Work File Assignments

The work file assignments are shown in a scrollable list containing work files with the numbers 1 to 32. The work file number is shown in the first column. When a work file name has already been defined for a work file number, this information (path and name) is shown in the Name column.

The following information can be changed:

Type

For each work file number, you can select another work file type. Possible values in the drop-down list box are:

Work File Type	Description
Default	Determines the file type from the extension for upward compatibility.
SAG	Binary format.
ASCII	Text files with records terminated by a carriage return and linefeed (CR/LF). When you choose the browse button next to this drop-down list box, you can change the properties for this work file type: a dialog box appears in which you can specify the following information: Code page You can specify the code page that is to be used for writing the work file (ICU code page name; IANA name recommended). When a code page is not defined here, the default code page defined with CP is used.
ASCII compressed	ASCII format where all trailing blanks are removed. When you choose the browse button next to this drop-down list box, you can change the properties for this work file type: a dialog box appears in which you can specify the following information: Code page You can specify the code page that is to be used for writing the work file (ICU code page name; IANA name recommended). When a code page is not defined here, the default code page defined with CP is used.
Entire Connection	With this work file type, you can read and write (for example, with the statements READ WORK FILE and WRITE WORK FILE) directly to a work file in Entire Connection format on the local disk. Note: No transfer to a PC is possible. The Entire Connection terminal is not used in this process.
Unformatted	A completely unformatted file. No formatting information is written (neither for fields nor for records). When you choose the browse button next to this drop-down list box, you can change the properties for this work file type: a dialog box appears in which you can specify the following information: Code page You can specify the code page that is to be used for writing the work file (ICU code page name; IANA name recommended). When a code page is not defined here, the default code page defined with CP is used.
Portable	Files which can handle dynamic variables exactly and can also be transported (for example, from a little endian machine to a big endian machine, and vice versa).
CSV	Comma-separated values. Each record is written to one line in the file. By default, a header is not written. The default character which is used to separate the data fields is a semicolon (;). When you choose the browse button next to this drop-down list box, you can change the properties for this work file type: a dialog box appears in which you can specify the following information: Header When set to "ON", a header with the Natural field names is written to the file. Separator character You can select a different separator character. If you require a separator character which is not listed in the drop-down list box, you can enter it in the text box of the drop-down list box. Code page You can specify the code page that is to be used for writing the work file (ICU code page name; IANA name recommended). When a code page is not defined here, the default code page defined with CP is used.

Note:
The browse button next to this drop-down list box is only available for specific work file types. See the information in the above table.

For information on the work file formats which result from a specific work file type, see Work File Formats in the Operations documentation.

Close mode

You can select a different close mode for each work file. Possible values in the drop-down list box are:

Close Mode	Description
Auto	This is the default setting. Work files are automatically closed at the end of a program or when the execution of the first called method in a method call hierarchy is terminated and the first called method was called over COM. If the first called method was called locally (not over COM), the work files are not closed. Example: Method A (called over COM) invokes method B which in turn invokes method C. When the execution of method A is terminated, all work files are closed.
User	Closing of work files is controlled by the user. The work file is closed, if one of the following conditions is met: a CLOSE WORK FILE statement is executed, a DEFINE WORK FILE statement is executed, the session terminates.

The following program example describes the user-controlled closing of work files. Note that the close mode must be first set in the parameter file.

DEFINE DATA
  LOCAL
  1 #OUT (A8)
END-DEFINE
*
#OUT := *PROGRAM
*
* Write to work file with close mode "user"
WRITE WORK 1 'OUTPUT PROGRAM: ' #OUT
*
* Write to work file with close mode "auto"
WRITE WORK 2 'OUTPUT PROGRAM: ' #OUT
*
* Close work file 1
* Work file 1 is user-controlled
CLOSE WORK FILE 1
*
END

Attributes

You can define different attributes for each work file. You can specify one attribute for each of the following categories:

Category	Possible Attributes	Default Attribute	Description
Append mode	NOAPPEND or APPEND	NOAPPEND	Decides whether new data overwrites the current data in the work file or whether new data is appended at the end of the current data.
Keep/delete work file after close	KEEP or DELETE	KEEP	Decides whether the work file is kept after closing it or whether it is deleted.
Write byte order mark (BOM)	BOM or NOBOM	NOBOM	Decides whether a byte order mark is written in front of the work file data. Only available for the work file types which write code page data: ASCII, ASCII compressed, Unformatted and CSV. For these work file types, the attribute BOM can only be set, if the code page UTF-8 is defined for the work file (see the description of the Type column). If a work file of another type is written or a code page other than UTF-8 is defined, the specification of the attribute BOM is ignored during runtime. See also Work Files and Print Files on Windows, UNIX and OpenVMS Platforms in the Unicode and Code Page Support documentation.

When you choose the browse button next to this text box, you can set these attributes in a dialog box. You can also set them in the table as described below.

You can enter a unique abbreviation for each attribute. The delimiter character can be one of the following: blank, comma(,) or semicolon (;). Example: "a, d" which stands for APPEND and DELETE.

You can only specify one attribute for each category. You can specify them in any sequence. When no attributes are specified in the table, the default values are used. You can also check the current values by invoking the dialog box.

Name

Specify the location (path and name) of the work file.

You can also choose the browse button next to this text box to select the work file from a dialog box.
