Or, maybe does not even support submodules?


In any event, that constraint does kill his example.  Perhaps it would be helpful to expand the answer a bit, without changing the conclusion.  Ian?s email quotes this explanation from the interp:

"If a module declares no separate module procedure, it cannot
have a useful submodule as such a submodule has nothing to
provide. Its module procedures and variables cannot be
referenced by any program.?

If the second sentence were expanded to  ?Because binding labels are not permitted on module procedures without interfaces in the ancestor module, its module procedures and variables cannot be referenced by any program.?,  it would be clearer that there is no back door available.

Cheers,
Bill
