DBCHCLN is the routine used for cleanup after your application program is finished using the database.

When your application calls DBCHCLN and the return code is zero, data structures allocated internally during the calls to CLI routines are de-allocated. At this point, if space is at a premium, de-allocate the DBCAREA.
