Dealing with Deleted Elements
There are three ways of denoting deleted items for a partial operation.
1.
The reference number of the deleted item can be specified. The reference number can be obtained by opening an MDB which includes the parent extract and navigating to that element, and then querying ('QUERY REFNO')
2.
If the 'HIERARCHY' keyword is used, then any deleted items within that hierarchy will be included.
3.
For primary elements, if the name of the deleted element has been reused, then flushing the element with the new name will flush the deleted element. For example, if you delete PIPE /PIPE1 and then recreates it, then flushing /PIPE1 will also flush the deleted pipe.
