## WRITE Usage

The `WRITE` statement is used to produce output in free format.

The `WRITE` statement differs from the `DISPLAY` statement in the following respects:

- Line overflow is supported. If the line width is exceeded for a line, the next field (or text) is written on the next line. Fields or text elements are not split between lines.

- No default column headers are created. The length of the data determines the number of positions printed for each field.

- A range of values/occurrences for an array is output horizontally rather than vertically.

Syntax Element Description:

Syntax Element | Description
--- | ---
`(rep)` | Report Specification: The notation `(rep)` is used to specify the identification of the report if multiple reports are to be produced by the program. 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 6. For information on how to control the format of an output report created with Natural, see Report Format and Control (in the Programming Guide).
- `NOTITLE` | Default Page Title Suppression: Natural generates a single title line for each page resulting from a `WRITE` statement. This title contains the page number, the time of day, and the date. Time of day is set at the beginning of program execution. This default title line may be overridden by using a `WRITE TITLE` statement, or it may be suppressed by using the `NOTITLE` option in the `WRITE` statement. Examples: Default title will be produced:
      WRITE NAME
- User title will be produced:
      WRITE NAME WRITE TITLE 'user-title'
- No title will be produced:
      WRITE NOTITLE NAME
Notes: 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. Page overflow is checked before execution of a `WRITE` statement. No new page with title or trailer information is generated during the execution of a `WRITE` statement.
`NOHDR` | Column Header Suppression: The `WRITE` statement itself does not produce any column headers. However, if you use the `WRITE` statement in conjunction with a `DISPLAY` statement, you can use the `NOHDR` option of the `WRITE` statement to suppress the column headers generated by the `DISPLAY` statement. The `NOHDR` option only takes effect if the execution of the `WRITE` statement causes a new page to be output. Without the `NOHDR` option, the column headers (if any) of the `DISPLAY` statement would be output on this new page; with `NOHDR` they will not.
`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 `WRITE` statement. Each parameter specified will override the corresponding parameter previously specified in a `GLOBALS` command, `SET GLOBALS` (in 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. See also: List of Parameters Example of Parameter Usage at Statement and Element (Field) Level Example 5 - WRITE Statement Using '=' and Parameters on Statement/Element (Field) Level
`nX`, `nT, x/y`, `T*field-name`, `P*field-name`, `'='`, `/` | Field Positioning Notation: See Field Positioning Notations in the section Output Format Definitions.
`'text'`, `'c'(n)`, `attributes`, `operand1`, `parameters` | Text/Attribute Assignment: See Text/Attribute Assignment in the section Output Format Definitions.

#### Field Positioning Notations

Syntax Element | Description
--- | ---
`nX` | Column Spacing: This notation inserts `n` spaces between columns. Example:
    WRITE NAME 5X SALARY
See also: Example 2 - WRITE Statement Using nX, nT Notation (below) Column Spacing - SF Parameter and nX Notation in the Programming Guide
`nT` | Tab Setting: The `nT` notation causes positioning (tabulation) to print position `n`. Backward positioning is not permitted. In the following example, `NAME` is printed beginning in position 25, and `SALARY` is printed beginning in position 50:
    WRITE 25T NAME 50T SALARY
See also: Example 2 - WRITE Statement Using nX, nT Notation (below) Tab Setting - nT Notation in the Programming Guide
`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 in the same line is not permitted. See also Positioning Notation x/y (in the Programming Guide).
`T*field-name` | Field Related Positioning: The notation `T*` is used to position to a specific print position of a field used in a previous `DISPLAY` statement. Backward positioning is not permitted. See also: Example 3 - WRITE Statement Using T* Notation (below) Tab Notation - T*field (in the Programming Guide)
`P*field-name` | Field and Line Related Positioning: The notation `P*` 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 printing mode. Backward positioning is not permitted. See also: Example 4 - WRITE Statement Using P* Notation (below) Tab Notation P*field (in the Programming Guide)
`'='` | Field Content Positioned behind Field Heading: When placed before a field, the equal sign `'='` results in the display of the field heading (as defined in the `DEFINE DATA` statement or in the DDM) followed by the field contents. See also: Example 1 - WRITE Statement Using '=', 'text', '/' Example 5 - WRITE Statement Using '=' and Statement/Element Parameters
`/` | Line Advance - Slash Notation: When placed between fields or text elements, a slash (/) causes positioning to the beginning of the next print line. Example:
    WRITE NAME / SALARY
Multiple slash (/) notations may be used to cause multiple line advances. See also: Example 1 - WRITE Statement Using '=', 'text', '/' (below) Line Advance - Slash Notation (in the Programming Guide) Example 2 - Line Advance in WRITE Statement (in the Programming Guide)

#### Text/Attribute Assignments

Syntax Element | Description
--- | ---
`'text'` | Text Assignment: The character string enclosed by single quotes is displayed. Example:
    WRITE 'EMPLOYEE' NAME 'MARITAL/STATUS' MAR-STAT
See also: Example 1 - WRITE Statement Using '=', 'text', '/' (below) Text Notation, Defining a Text to Be Used with a Statement in the Programming Guide
`'c'(n)` | Character Repetition: The character enclosed by single quotes is displayed `n` times immediately before the field value. For example:
    WRITE '*' (5) '=' NAME
results in
    ***** SMITH
See also Text Notation, Defining a Character to Be Displayed n Times before a Field Value (in the Programming Guide).
`attributes` | Field Representation and Color Attributes: It is possible to assign various attributes for text/field display. These attributes and the syntax that may be used are described in the section Output Attributes below. Examples:
    WRITE 'TEXT' (BGR)
    WRITE 'TEXT' (B)
    WRITE 'TEXT' (BBLC)
`operand1` | Field to be Written: `operand1` specifies the field whose content is to be written in this place.
`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 may not be split between two statement lines. See also: List of Parameters Example of Parameter Usage at Statement and Element (Field) Level

#### Output Attributes

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

| `AD`=ad-value `CD`=cd-value `PM`=pm-value |
| ad-value cd-value |

Where:

`ad-value`, `cd-value` and `pm-value` denote the possible values of the corresponding session parameters `AD`, `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=`.

## Syntax 2 - Using Predefined Form/Map

`WRITE` [(rep)] [`NOTITLE`] [`NOHDR`] [`USING` ] |  | `FORM` |  | operand1 |  | operand2 |
`MAP` | `NO PARAMETER`

For an explanation of the symbols used in the syntax diagram, see Syntax Symbols.

Operand Definition Table:

Operand | Possible Structure | Possible Formats | Referencing Permitted | Dynamic Definition
--- | --- | --- | --- | ---
operand1 | C | S |  |  |  | A |  |  |  |  |  |  |  |  |  |  |  |  | no | no
operand2 |  | S | A | G | N | A | U | N | P | I | F | B | D | T | L |  |  |  | yes | no

Syntax Element Description:

Syntax Element | Description
--- | ---
`[USING] FORM` `[USING] MAP` | Use of Predefined Form/Map Layout: This option may be used to indicate that a form/map layout previously defined with the map editor is to be used. A map layout used in a `WRITE` statement does not automatically create a new page each time the map is output. For the line spacing, the `LS` parameter setting must be 1 byte greater than the `LS` setting defined in the map.
`operand1` | Form/Map Name: `operand1` is the name of the form/map to be used.
`operand2` | Field to be Written: `operand2` is the name(s) of the field(s) to be written. If `operand1` is a constant and `operand2` is omitted, the fields are taken from the map source at compilation time. The fields must agree in number, sequence, format, length and (for arrays) number of occurrences with the fields in the referenced form/map; otherwise, an error occurs. If `FORM` or `MAP` does not require any parameters, specify the `NO PARAMETER` option.
`NOTITLE/NOHDR` | Title Line/Column Header Suppression: `NOTITLE` and `NOHDR` are described under Syntax 1 of the `WRITE` statement.
