Replacement of obsolete «Import/Export to-from Memory ID» operator

Hi, ABAP Experts

Import/Export to-from Memory ID is one of the main approaches to pass data between ABAP-programs. The problem is that this statement has been marked as obsolete since ECC 6.0 (at least since end of 2007). On some comments you can see the recommendations to use SAP Memory instead, but this way is not ideal due to more wide scope, which can be potentially dangerous.

So, my question is what is the correct approach to pass data between two ABAP-programs (SE38) in our days (mid 2013)? Should we still use Import/Export to-from Memory ID or there is more correct way to implement such task, which is safety and isn't obsolete?

Thanks.
