The following diagram presents the syntax of the HDELETE command for both SMS-managed and non-SMS-managed data sets:

               .-,-------------------------.                                               
               V                           |    (2)                                        
>>-HDELETE--(----dsname--+---------------+-+--)------+-------+--+--------+--+----------+-><
                         |           (1) |           '-PURGE-'  +-WAIT---+  '-EXTENDRC-'   
                         '-/password-----'                      '-NOWAIT-'                 

1. Password does not apply to SMS-managed data sets.
2. Parentheses are required only when multiple data set names are specified.
