ILE provides a common basis for:
It gives RPG users much better control over resources than was previously possible.
ILE programs and service programs are activated into activation groups which are specified at program-creation time. The process of getting a program or service program ready to run is known as activation. Activation allocates resources within a job so that one or more programs can run in that space. If the specified activation group for a program does not exist when the program is called, then it is created within the job to hold the program's activation.
An activation group is the key element governing an ILE application's resources and behavior. For example, you can scope commitment-control operations to the activation group level. You can also scope file overrides and shared open data paths to the activation group of the running application. Finally, the behavior of a program upon termination is also affected by the activation group in which the program runs.
For more information on activation groups, see Managing Activation Groups.
You can dynamically allocate storage for a run-time array using the bindable APIs provided for all ILE programming languages. These APIs allow single- and mixed-language applications to access a central set of storage management functions and offer a storage model to languages that do not now provide one. RPG offers some storage management capabilities using operation codes. For more information on storage management, see Managing Dynamically-Allocated Storage.
