The LOAD control statement is used for recovery purposes to load the database from a sequential, previously unloaded file. You define the input (unloaded) copy of the database with DD statement RMOLOAD.
The LOAD control statement with an UNLOAD control statement can be used to reorganize a database and reclaim blocks in the database that are allocated but are not currently being utilized.
The high-level name of the database must have been defined previously with the NAME control statement (or the PARM parameter of the EXEC JCL statement). The output database must be a newly created, empty database.
If LOAD is attempted against a database that already contains data then a message RMODBM11 TO DATABASE IS NOT EMPTY is issued and the step terminates with a return code 16.
