Retrieves the present record from a file and locks the record. If the record
is already locked by another user, it waits until the record becomes free.
This is particularly useful after having positioned the file pointer directly
ahead of a record with the verb BEGIN THIS, enabling you to retieve the
previous record in a file.
The reference of the record is written to the target noun REFERENCE.
