Provide detection of program termination for RPG and Other ILE Languages

Provide a register call stack entry termination user exit procedure API that runs automatically when the call stack entry for which it is registered is ended also by a normal return to the caller.
API CEERTX does this only on an abnormal program termination.
API CEE4RAGE does this only on an activation group termination.

This should be possible also for a normal program termination.

Use Case:

This functionality is useful for cleaning activity like memory deallocation or deleting temporary objects at the termination of the program.

    .IBM does not intend to provide a solution to this request at this time, so it is being closed. For ILE RPG, the ON-EXIT mechanism can be used. For C++, the destructor mechanism can be used. For other languages, an ILE RPG or C++ wrapper procedure could be used.

    The CAAC has reviewed this requirement and recommends that IBM view this as a “nice to have” low priority feature.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    IBM has modified some of the information in this request. Please contact us if you have any questions. In particular. the Headline was modified to include other ILE languages in addition to RPG. IBM will be evaluating this request as an API Enhancement for RPG and possibly other ILE languages.

    The ON-EXIT feature that was recently added to RPG for 7.2 and 7.3 may satisfy this requirement for RPG procedures. The ON-EXIT opcode starts a section of code that will run whenever the procedure ends, whether normally or abnormally.
