Syntax

── EXCLUDE ─┬─<file title>─┬───────────────────────┬───────────────────┤
            │              └─<sequence range list>─┤
            └─<sequence range list>──<file title>──┘

Explanation

The EXCLUDE command causes any line in the work file with the same sequence number as a line in the specified <file title> to be deleted. Unmatched lines in the excluded file are ignored. The UPDATE option is implicitly invoked after the EXCLUDE option has been executed.

The EXCLUDE command is particularly helpful when used in combination with the FIND command FILE option. This command should not be used with type DATA or CDATA files because these files do not have sequence numbers stored in the text.
