       /DELETE=(verb[,...])

    Specifies /DELETE mode to delete verbs from the command table you
    are modifying.

    You can use the /DELETE qualifier to delete a verb in either
    your process command table or in a command table file specified
    with the /TABLE qualifier. If you do not use the /TABLE qualifier
    to specify an alternate command table, the default is to delete
    verbs from your process command table. If you do not use the
    /OUTPUT qualifier to specify an output file, the default is to
    return the modified command table to your process.

    The verb specifies a verb to be deleted. If you specify two
    or more verbs, separate them with commas and enclose the list
    in parentheses. If you specify only one verb, you can omit the
    parentheses.

    You cannot use the /LISTING, /OBJECT, or /REPLACE qualifiers in
    /DELETE mode.
