Function

The DISPLAY statement is used to specify the fields to be output on a report in column format. A column is created for each field and a field header is placed over the column.

Note:
The statements WRITE and PRINT can be used to produce output in free (non-column) format.

Syntax Description

Syntax Element Description
(rep)
Report Specification:

The notation (rep) may be used to specify the identification of the report for which the DISPLAY statement is applicable.

As report identification, a value in the range 0 - 31 or a logical name which has been assigned using the DEFINE PRINTER statement may be specified.

If (rep) is not specified, the statement will apply to the first report (Report 0).

If this printer file is defined to Natural as PC, the report will be downloaded to the PC, see Example 8.

For information on how to control the format of an output report created with Natural, see Report Format and Control in the Programming Guide.

Output Format Definitions:

For details, see Output Format Definitions below.

/
Line Advance - Slash Notation:

When specified within a text element, a slash (/) causes a line advance for the text displayed.

When specified between output elements, it causes the output element specified by the slash (/) to be placed vertically within the same column. The header for this column will be constructed by placing the headers of the vertically displayed elements vertically above the column.

[NOTITLE] [NOHDR]

[AND] [GIVE] [SYSTEM] FUNCTIONS

[(statement-parameters)]

Syntax Element Description:

Syntax Element Description
NOTITLE
Default Page Title Suppression:

By default, Natural generates a single title line for each page resulting from a DISPLAY statement. This title contains the page number, the time of day, and the date. Time of day is set at the beginning of the program execution (TP mode) or at the beginning of the job (batch mode). The default title line may be overridden by using a WRITE TITLE statement, or it may be suppressed by specifying the keyword NOTITLE in the DISPLAY statement.

Examples:

  • Default title will be produced: 

    DISPLAY NAME

  • User title will be produced: 

    DISPLAY NAME WRITE TITLE 'user-title'

  • No title will be produced: 

    DISPLAY NOTITLE NAME

Note:
If the NOTITLE option is used, it applies to all DISPLAY, PRINT and WRITE statements within the same object which write data to the same report.

NOHDR
Column Headers:

Column headers are produced for each field specified in the DISPLAY statement using the following rules:

  • The header text may be explicitly specified in the DISPLAY statement before the field name. For example: 

    DISPLAY 'EMPLOYEE' NAME 'SALARY' SALARY

  • If you do not specify an explicit header for a field, the header as defined in the DEFINE DATA statement will be used.

  • If for a database field no header is defined in the DEFINE DATA statement, the default header as defined in the DDM will be used.

  • If no default header is defined in the DDM, the field name will be used as header.

  • If for a user-defined variable no header is defined in the DEFINE DATA statement, the variable name will be used as header. See also the DEFINE DATA statement for header definition. 

    DISPLAY NAME SALARY #NEW-SALARY

  • Natural always underlines column headings and generates one blank line between the underlining and the data being displayed.

  • If there are multiple DISPLAY statements in a program, the first DISPLAY statement determines the column header(s) to be used; this is evaluated at compilation time.

Column Header Suppression:

To suppress the column header for a single field

  • Specify the following characters (apostrophe-slash-apostrophe) before the field name: 

    '/'

    For example: 

    DISPLAY '/' NAME 'SALARY' SALARY
To suppress all column headers

  • Specify the keyword NOHDR: 

    DISPLAY NOHDR NAME SALARY

Notes:

  1. NOHDR only takes effect for the first DISPLAY statement, as subsequent DISPLAY statements cannot create column headers anyhow.
  2. If both NOTITLE and NOHDR are used, they must be specified in the following order: DISPLAY NOTITLE NOHDR NAME SALARY
GIVE SYSTEM FUNCTIONS
Natural System Function Usage:

The GIVE SYSTEM FUNCTIONS clause is used to make available the following Natural system functions: AVER, COUNT, MAX, MIN, NAVER, NCOUNT, NMIN, SUM, TOTAL. These are evaluated when the DISPLAY statement containing the GIVE SYSTEM FUNCTIONS clause is executed.

These functions may then be referred to in a statement executed as a result of an end-of-page condition.

Notes:

  1. Only one DISPLAY statement per report may contain a GIVE SYSTEM FUNCTIONS clause. When system functions are evaluated from a DISPLAY statement, they are evaluated on a page basis, which means that all functions (except TOTAL) are reset to zero when a new page is initiated.
  2. When system functions are used within a DISPLAY statement within a subroutine, the end-of-page processing must occur within the same routine.
  3. In place of the keyword GIVE, the keyword GIVING may be used.

See also Example 2 - DISPLAY Statement Using GIVE SYSTEM FUNCTIONS Clause.

statement-parameters
Parameter Definition at Statement Level:

One or more parameters, enclosed within parentheses, may be specified at statement level, that is, immediately after the DISPLAY statement.

Each parameter specified will override the corresponding parameter previously specified in a GLOBALS command, SET GLOBALS (Reporting Mode only) or FORMAT statement.

If more than one parameter is specified, they must be separated by one or more blanks from one another. Each parameter specification must not be split between two statement lines.

Note:
The parameter settings applied here will only be regarded for variable fields, but they have no effect on text-constants. If you would like to set field attributes for a text-constant, they have to be set explicitly for this element, see Parameter Definition at Element (Field) Level.

Field Positioning Notations

Syntax Element Description
nX
Column Spacing:

This notation inserts n spaces between columns. n must not be zero.

Example:

DISPLAY NAME 5X SALARY

See also:
nT
Tab Setting:

The nT notation causes positioning (tabulation) to display position n. Backward positioning is not permitted.

In the following example, NAME is displayed beginning in position 25, and SALARY beginning in position 50: 

DISPLAY 25T NAME 50T SALARY

See also:
x/y
x/y Positioning:

The x/y notation causes the next element to be placed x lines below the output of the last statement, beginning in column y. y must not be zero. Backward positioning is not permitted.

T*field-name
Field Related Positioning:

The T* notation is used to position to a specific print position of a field used in a previous DISPLAY statement. Backward positioning is not permitted.

P*field-name
Field and Line Related Positioning:

The P* notation is used to position to a specific print position and line of a field used in a previous DISPLAY statement. It is most often used in conjunction with vertical display mode. Backward positioning is not permitted.

Override Column Heading Assignment

Syntax Element Description
'text'  

'/'

Text Assignment:

If placed immediately before a field, the text enclosed by single quotes overrides the column heading.

The slash character '/' before a field causes the header for the field to be suppressed. 

DISPLAY 'EMPLOYEE' NAME 'MARITAL/STATUS' MAR-STAT

If multiple 'text' elements are specified before a field name, the last 'text' element will be used as the column header and the other text elements will be placed before the value of the field within the column.

See also:
'c'(n)
Character Repetition:

The character enclosed by single quotes is displayed n times immediately before the field value. For example: 

DISPLAY '*' (5) '=' NAME

results in 

***** SMITH

Output Attributes

attributes indicates the output attributes to be used for text display. Attributes can be:

AD=ad-value
BX=bx-value
CD=cd-value
PM=pm-value

ad-value
cd-value

Where:

ad-value, bx-value, cd-value and pm-value denote the possible values of the corresponding session parameters AD, BX, CD and PM described in the relevant sections of the Parameter Reference documentation.

The compiler actually accepts more than one attribute value for an output field. For example, you can specify: AD=BDI. In such a case, however, only the last value applies. In the given example, only the value I becomes effective and the output field is displayed intensified.

For an alphanumeric/Unicode constant (Natural data format A or U), you can specify ad-value and/or cd-value without preceding CD= or AD=, respectively. The single value entered is then checked against all possible CD values first. For example: a value of IRE will be interpreted as intensified/red but not as intensified/right-justified/mandatory. You cannot combine a single cd-value or ad-value with a value preceded by CD= or AD=.

Vertical/Horizontal Display

The VERT clause may be used to cause multiple field values to be positioned underneath one another in the same column. In vertical mode, a new column may be initiated by specifying the keyword VERT or HORIZ.

The column heading in vertical mode is controlled using the entry or entries specified with the AS clause as described below.

Syntax Element Description
VERTICALLY
DISPLAY VERT without AS Clause:
Vertical column orientation. No column heading is produced if the AS clause is omitted. 
DISPLAY VERT NAME SALARY

For an example, see DISPLAY VERT without AS Clause in the Programming Guide.

AS 'text'
DISPLAY VERT AS 'text' Clause:
Vertical column orientation. If AS 'text' is specified, the text enclosed by single quotes is used as the column heading.

For an example, see DISPLAY VERT AS 'text' in the Programming Guide.

The slash character / in the character string of 'text' will cause multiple lines of column headings. 

DISPLAY VERT AS 'LAST/NAME' NAME
AS 'text' CAPTIONED
DISPLAY VERT AS 'text' CAPTIONED Clause:
Vertical column orientation. If AS 'text' CAPTIONED is specified, 'text' is used as the column heading and the standard heading text or field name is inserted immediately before the field value in each detail display line. 
DISPLAY VERT AS 'PERSONS/SELECTED' CAPTIONED NAME FIRST-NAME

For an example, see DISPLAY VERT AS 'text' CAPTIONED in the Programming Guide.

AS CAPTIONED
DISPLAY VERT AS CAPTIONED Clause:
Vertical column orientation. If AS CAPTIONED is specified, the standard heading text for the field (either heading text or the field name) will be used as the column heading. 
DISPLAY VERT AS CAPTIONED NAME FIRST-NAME
HORIZONTALLY
DISPLAY HORIZ Clause:
Horizontal column orientation. This is the default display mode.

Vertical and horizontal column orientation may be intermixed by using the respective keyword.

To suspend vertical display for a single output element, you may place a dash (-) in front of the element. For example: 

DISPLAY VERT NAME - FIRST-NAME SALARY

In the above example, FIRST-NAME will be output horizontally next to NAME, while SALARY will be output vertically again, i.e. below NAME.

The standard display mode is horizontal. A column is constructed for each field to be displayed.

Column headings are obtained and used by Natural according to the following priority:

  1. heading 'text' supplied in the DISPLAY statement;

  2. the default heading defined in the DDM (database fields), or the name of a user-defined variable;

  3. the field name as defined in the DDM (if no heading text was defined for the database field).

For group names, a group heading is produced for the entire group. When specifying a group, only the heading for the entire group may be overridden by a user-specified heading.

The maximum number of column header lines is 15.

Line size overflow is not permitted for output resulting from a DISPLAY statement. If a line overflow occurs, an error message is issued.

parameters
Parameter Definition at Element (Field) Level:

One or more parameters, enclosed within parentheses, may be specified at element (field) level, that is, immediately after operand1. Each parameter specified in this manner will override the corresponding parameter previously specified at statement level or in a GLOBALS command, SET GLOBALS (in Reporting Mode only) or FORMAT statement.

If more than one parameter is specified, one or more blanks must be placed between each entry. An entry must not be split between two statement lines.

Defaults Applicable for a DISPLAY Statement

The following defaults are applicable for a DISPLAY statement:

  • Report Width
    The width of the report defaults to the value set when Natural is installed. This default value is normally 132 in batch mode or the line length of the terminal in TP mode. It may be overridden with the session parameter LS. In TP mode, line size (LS) and page size (PS) parameters are set by Natural based on the physical characteristics of the terminal type in use.

  • Terminal Screen Output
    When the DISPLAY output is displayed on a terminal (emulation) screen, the output begins in physical Column 2 (because Column 1 must be reserved for possible use as an attribute position on a 3270-type terminal).

  • Printout on Paper
    When the DISPLAY output is printed on paper, the printout begins in the leftmost column (Column 1).

  • Spacing Factor
    The default spacing factor between elements is one position. There is a minimum of one space between columns (reserved for terminal attributes). This default may be overridden with the session parameter SF.

  • Field Output
    The length of the field or the field heading, whichever is greater, determines the column width for the report (unless the HW parameter is used).

    • If the field is longer than the heading, the heading will be centered over the column unless the HC=L or HC=R parameter is used to produce a left-justified or right-justified heading.

    • If the heading is longer than the field, the field will be left-justified under the heading.

    • The values contained in the field are left-justified for alphanumeric fields and right-justified for numeric fields.

    • Numeric fields may be displayed left-justified by specifying AD=L.

    • Alphanumeric fields may be displayed right-justified by specifying AD=R.

    • In a vertical display, the longest data value or heading among all fields determines the column width (unless the HW parameter is used).

  • Sign
    One extra high-order print position is reserved for a sign when printing a numeric field. The session parameter SG may be used to suppress the sign position.

  • Page Overflow
    Page overflow is checked before execution of a DISPLAY statement. No new page title or trailer information is generated during the execution of a DISPLAY statement.
