The DELETE COLLATING_SEQUENCE statement deletes the named collating
 sequence.

 If you have defined a global field or database using the named
 collating sequence, you cannot delete the collating sequence.

 DELETE COLLATINGSEQUENCE ──> sequence-name.

 You must execute this statement in a read/write transaction.  If
 there is no active transaction and you issue this statement, Rdb/VMS
 starts a read/write transaction implicitly.

 Other users are allowed to be attached to the database when you issue
 the DELETE COLLATING_SEQUENCE statement.
