Specifies how a field’s ListWidth is treated in a LIST command.
Syntax
SET OUTPUT FIELDLISTWIDTH ON|OFF
Comments
The OUTPUT FIELDLISTWIDTH option is set ON by default.
When OUTPUT FIELDLISTWIDTH is ON, the LIST command formats output according to each field’s established ListWidth. Setting FIELDLISTWIDTH to OFF causes the software to ignore the established ListWidth and to format all fields to their maximum length. Fields with an established ListWidth of -1 therefore appear in the output.

SELECT
Controls how special characters in unstructured application documents are treated.
Syntax
SET SPECIALSCAN ON|OFF
Comments
The SET SPECIALSCAN command is set ON by default.
When SPECIALSCAN is ON, the backslash () and asterisk (*) characters have special meanings when they appear in an unstructured application document that is being used as a data source in an ADD or CHANGE command. Setting SPECIALSCAN to OFF causes the backslash and asterisk to be treated as normal characters by these commands.

CHANGE
SET DELIMITER
Translates carriage return/line feed sequences.
Syntax
SET EOLNTRANSLATE string
Parameters
| string | Any expression that evaluates to a character string from one to five characters in length. If string is longer than five characters, only the first five characters are used. |
Comments
If the software encounters a carriage return/line feed combination in a database field when outputting that field to an application document, the carriage return/line feed combination is substituted for string. If the software encounters string during a read of an application document, the string generates a carriage return/line feed combination.
In operations that write data to an application document, the software substitutes the specified EOLTRANSLATE string for each carriage return/line feed sequence detected in the output from a single field. In operations that read data from an application document, the software substitutes a carriage return/line feed sequence for each EOLTRANSLATE string it detects in a single field.
Determines if compiled versions of application programs are to be executed.
Syntax
SET [LOCAL] RUNTIME ON|OFF
Comments
Specifies if the Runtime system is to be available for program execution. When RUNTIME is set OFF, compiled programs are treated as if they are not compiled.
A SET LOCAL RUNTIME command can be used inside a program to make the Runtime system locally available to that program when RUNTIME is globally switched off. If that program subsequently calls another program, however, the Runtime system is unavailable within the second program.
The SET RUNTIME command is not affected by the SET RESET and SET RESTORE commands.

Controls tracing of retrieval strategy information.
Syntax
SET STRATEGY ON|OFF
Comments
The SET STRATEGY command is OFF by default.
When SET STRATEGY is set ON, the software displays the chosen retrieval strategy for each command that accesses the database (i.e., FIND, COMPUTE, LIST, REPORT FROM, CHANGE, ADD, DELETE, SELECT, UPDATE). The retrieval strategy information is written to the destination specified in the last SET TRACE OUTPUT command.

Controls the display of a XMLHEADER.
Syntax
SET XMLHEADER ON|OFF
Comments
When outputting data using the XML or XMLSIMPLE formats, a standard ISO header can be attached to the resulting document.
Example
set save
set output format xmlsimple
set XMLHEADER on
set output MyDoc
list 1 Docs
set restore

SET OUTPUT FORMAT
Switches the display of the text-entry cursor on or off.
Syntax
SET CURSOR ON|OFF
Comments
The CURSOR option is set ON by default.
When CURSOR is ON, the text-entry cursor is displayed on the screen when a text form field has focus. You can switch the text-entry cursor off when its logical location is already indicated by enhanced display attributes in the form field (specified using the FORM SET command). For example, you could switch the text-entry cursor off in menus.
Some terminal types do not enable the text-entry cursor to be switched off; in these cases, SET CURSOR OFF has no effect. In some environments with attached terminals, the sequences that turn the text-entry cursor on and off must be included in your terminal description file.

CURSOR
Controls the use of pauses during LIST output.
Syntax
SET PAUSE ON|OFF
Comments
The PAUSE option is set OFF by default.
When you set PAUSE ON, LIST output pauses after each “page” (i.e., the number of lines specified in the current PAGESIZE setting).
During a pause at the terminal, the message Press to continue, q to quit appears. (This message can be altered with ZIMLANG, the Language Customizer utility, if desired.)
Example
set output printer
set pause on
set pagesize 40
set pagewidth 120
list all Employees sorted by Department
The above SET PAUSE command ensures that the printer stops after each page, enabling you (for example) to manually feed a special form for each page of output.

SET HEADINGS
SET PAGEWIDTH
Enables or suppresses the display of all system messages.
Syntax
SET MESSAGES ON|OFF
Comments
The MESSAGES option is set ON by default.
When MESSAGES is ON, all system messages (errors, warnings, information) are displayed. Setting MESSAGES to OFF suppresses the display of all messages.
The display of specific message types may be turned on or off using the SET ERRORS, SET INFORMATION, and SET WARNINGS commands.
The SET MESSAGES command has no effect on the logging of messages in the “error trace” file. Message logging is governed by the configuration option error trace.
Example
set messages on
set warnings off
The preceding commands set error and information messages on, but warnings off.
See Also
SET ERRORS
Enables or suppresses the display of error messages.
Syntax
SET ERRORS ON|OFF
Comments
The ERRORS option is set ON by default.
When ERRORS is ON, error messages are displayed. Setting ERRORS to OFF suppresses the display of such messages. Error messages are of the form:
*** Error*** . . .
or:
***Zim System Error*** . . .
All types of messages can be simultaneously turned on or off with a SET MESSAGES command.
SET ERRORS has no effect on the logging of messages in the “error trace” file as this logging is always on and cannot be disabled.
Example
set messages on
set errors off
The preceding commands set warning and information messages on, but error messages off.
