Function

The PRINT statement is used to produce output in free format.

The PRINT statement differs from the WRITE statement in the following aspects:

  • The output for each operand is written according to the value content rather than the length of the operand. Leading zeros for numeric values and trailing blanks for alphanumeric values are suppressed. The session parameter AD defines whether numeric values are printed left or right justified. With AD=L, the trailing blanks of a numeric value are suppressed. With AD=R, the leading blanks of a numeric value are printed.

  • If the resulting output exceeds the current line size (LS parameter), the output is continued on the next line as follows: An alphanumeric constant or the content of an alphanumeric variable (without edit mask) is split at the rightmost blank or character which is neither a letter nor a numeric character contained on the current line. The first part of the split value is output to the current line, and the second part is written to the next line. Leading blanks in the second part are removed. As a consequence, empty lines are suppressed.

    For all other operands, the entire value is written to the next line.

Syntax Element Description:

Syntax Element Description
(rep)
Report Specification:

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

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 PRINT 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 2.

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 PRINT statement. This title contains the page number, the time of day, and the date. Time of day is set at the beginning of the session (TP mode) or at the beginning of the job (batch mode). This default title line may be overridden by using a WRITE TITLE statement, or it may be suppressed by specifying the NOTITLE clause in the PRINT statement. Examples:

  • Default title will be produced: 

    PRINT NAME

  • User title will be produced: 

    PRINT NAME WRITE TITLE 'user-title'

  • No title will be produced: 

    PRINT NOTITLE NAME

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 Header Suppression:

The PRINT statement itself does not produce any column headers. However, if you use the PRINT statement in conjunction with a DISPLAY statement, you can use the NOHDR option of the PRINT statement to suppress the column headers generated by the DISPLAY statement. The NOHDR option only takes effect if the execution of the PRINT 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 PRINT statement or an element being displayed.

Each parameter specified in this manner will override any previous parameter specified in a GLOBALS command, SET GLOBALS (in Reporting Mode only) or FORMAT statement. If more than one parameter is specified, the parameters must be separated from one another by one or more blanks. A parameter entry must not be split between two statement lines.

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.

Example of Parameter Usage at Statement and Element (Field) Level 

DEFINE DATA LOCAL
1 VARI (A4)     INIT <'1234'>                  /*     Output 
END-DEFINE                                     /*    Produced

PRINT (AD=U)    'Text'           VARI          /*    Text 1234
PRINT           'Text' (AD=U)    VARI (AD=U)   /*    Text 1234
PRINT           'Text' (AD=U)    VARI          /*    Text 1234

Field Positioning Notations

Syntax Element Description
nX
Column Spacing:
This notation inserts n spaces between columns. 
PRINT NAME 5X SALARY
nT
Tab Setting:

The nT notation causes positioning (tabulation) to print position n. Backward positioning results in a line advance.

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

PRINT 25T NAME 50T SALARY
/
Line Advance - Slash Notation:

When placed between fields or text elements, a slash (/) causes positioning to the beginning of the next print line. 

PRINT NAME / SALARY

Text/Attribute Assignment

Syntax Element Description
'text'
Text Assignment:

The character string enclosed by single quotes is displayed. 

PRINT 'EMPLOYEE' NAME 'MARITAL/STATUS' MAR-STAT
'c' (n)
Character Repetition:

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

PRINT '*' (5) '=' NAME
'='
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. 

PRINT '=' NAME
operand1
Field to be Printed:

As operand1 you specify the field to be printed.

parameters
Parameter Definition at Element (Field) Level:

One or more parameters (see table above), enclosed within parentheses, may be specified immediately after operand1.

Each parameter specified in this manner will override any previous parameter 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.

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=.
