On the other hand, my restoreh5 is a function returning a structure. Just for curiosity, what is the trick with the native RESTORE procedure? How does it make the loaded variables available in memory after the execution? It behaves like a batch file that takes some input (filename, keywords) or as a procedure with a silent STOP before the END.

RESTORE is part of the C-level API (rather than .pro code) so it is able to create variables in whatever scope it wants. It is probably using the equivalent of the exposed entry point IDL_FindNamedVariable(). (See http://www.harrisgeospatial.com/docs/LookUpVariablesCurrentS cope.html).
