This section describes the enhancements made to ILE RPG in V6R1.


When THREAD(*CONCURRENT) is specified on the Control specification of a module, it provides ability to run concurrently in multiple threads:

  • Multiple threads can run in the module at the same time.
  • By default, static variables will have defined threads which will have its own copy of the static variable.
  • Individual variables can be defined to be shared by all threads                                                                                                                           using STATIC(*ALLTHREAD).
