JUSTIFY
JUSTIFY
Used to move data within a field to the left or right boundary of the field, or center it
within the field.
Syntax
[JUSTIFY {LEFT
RIGHT
CENTER}]
Parameters
LEFT The data in the current field is shifted to the left.
RIGHT The data in the current field is shifted to the right.
CENTER The data in the current field is centered in the field.
Discussion
The JUSTIFY statement can be used to format data entered into or moved to any field. (For
automatic formatting, refer to the SET command earlier in this section.) As is true of all
formatting statements, JUSTIFY has an immediate effect on the data in the memory buffer;
the formatted data is then available for display or copying into the application. When the
user enters data into a field for which formatting is specified, the data is formatted as soon
as
ENTER or an appropriate function key is pressed. Thus, FORMSPEC formatting is done
before data is written to the data or batch file. (In contrast, reformatting through
REFORMAT, described in Section 5, is done after data is collected, edited, and written to
the batch file.)
Example
If the data cannot be centered exactly, the extra blank is on the right.
