Now as I understand it IBM i 7.1 lets you compile RPG modules with
teraspace as the storage model. Does that also mean that the CEE API
uses memory from teraspace and does it mean that I can use 1TB with
the same api and just a different compile setting (
STGMDL(*TERASPACE) ) ? I have no chance to test this as we are on 6.1
still.


There are two aspects to the storage model changes for RPG in 7.1.

1. Allocating teraspace heap storage using %ALLOC etc.
2. Running in the teraspace storage model.

If you only need teraspace heap storage, then use the ALLOC keyword. Only use STGMDL(*TERASPACE) if you really need to. The reason is that any one activation group can run either teraspace storage model or single-level storage model. If you just change one program to use the teraspace storage model, it will have to run in a different activation group from the other programs. So using STGMDL(*TERASPACE) requires full understanding of the existing activation groups used by an application, and careful planning of the changes required by any programs or service programs that will always use the teraspace storage model.
