A description of the syntax clauses follows:

COLUMN

Specifies the columns to compare from and thru. If omitted, columns 1-72 are used.

OUTPUT

Specifies which records are to be output. The default is CHANGES only. The options are: HISTORY (shows the existing member together with both inserts and deletes), and NEW (shows the new member, highlighting inserts only).

FORMAT

Specifies the output format. The default is DISPLAY that writes the output to file NDVRLST. The syntax listing is produced first, followed by the original output file in report format - with carriage control and page headings. The FILE option (i.e., BROWSE) writes the data to DDname NDVRPCH without page headings.

PAD

PAD is applicable to variable length records only. The default is BLANK (which pads short records with blanks up to the compare length). The options are NULL (which pads with binary zeros) or "x" (which pads with the specified single character).

SIZE

Specifies a file-size estimate for the sort. By default, this option is ignored.

TITLE

Appears before the first data line as a line of asterisks, followed by the title string and another line of asterisks. Useful if FORMAT=FILE.
