WORDWRAP

WORDWRAP operator divides a long character string into segments and sends them to successive lines of a 4gl report:

Here

• string is a character string that will be printed in the report output
• TEXT variable is the name of a TEXT variable that will be printed in the report output
• temporary variable is an integer expression that returns a value specifying the absolute position of a temporary right margin (this position is calculated in characters starting from the left margin)

WORDWRAP automatically wraps successive segments of long character strings onto successive lines in a 4gl report:

• Any character string value or a TEXT value that is too long to fit between the current character position and the specified or default right margin is divided into segments and displayed between temporary margins:
• the current character position becomes the temporary left margin.
• The size of the right margin is 132 characters by default or can be set by RIGHT MARGIN temporary or in the RIGHT MARGIN clause of the OUTPUT section of the report definition.

WORDWRAP RIGHT MARGIN is used to set a temporary right margin.

This temporary margin is calculated starting from the left side of the page. The value of the temporary right margin cannot be smaller than the current character position and greater than 132 (or the size of the right margin specified in the OUTPUT section). The current character position becomes the temporary left margin.

Here the PRINT statement specifies that a character string stored in a variable called my_text must be printed out between the temporary left margin set as COLUMN 10 and the temporary right margin set as COLUMN 70:

PRINT COLUMN 10, my_text WORDWRAP RIGHT MARGIN 70

Temporary margin values override the margin values from the OUTPUT section or the default margins. The margins of the OUTPUT section or the default margins are restored after the PRINT statement was executed.
