Yep, that explains it - the prolog code is where the native routine is
called so it has not finished when the second interpreter tries to load
it again. It is interesting that if I just use the current interpreter
to call the program - context->CallProgram(...) - from the native
routine, the lock does not occur. Of course the current interpreter
doesn't have the options I want. Hummm...

OK, that is what I expected.
I have now determined why my earlier attempts failed and it was
not due to the bad return code. I'm attempting to run the same
program recursively under the second/new interpreter but it hangs
until I double control-c. The program has a Requires directive
which is where the native Routine is called. I have made copies
of the program file and the requires file and modified the copied
program to specify the copied requires file. With these changes
(and having the native routine run the copied program under the
new interpreter), everything works as I had expected. So, I'm
guessing there is a file lock involved somewhere, probably on the
Requires file. Is this intentional? I'm pretty sure I've written
recursive program before but perhaps not :-(.
it the call is occurring from the prolog portion of the ::requires
file that's probably what's happening. ::requires are loaded only once
so the package manager detects that the file has already been loaded
but the prolog portion has not finished running yet so it waits for it
to complete.

Oh, and one other question - does the new interpreter share
the global environment or is it totally independent?

You are right! The interpreter WAS actually created and I
was able to get it to run a simple Rexx script. Thanks! And
I guess I should get a new 5.0.0 build; I'm on 2 May 2017.

I've been experimenting with the ooRexx Native API and
have run across a problem. I have created a native
routine which runs successfully. I now want to have
that native routine create another interpreter instance
with options. However, the RexxCreateInterpreter()
function returns 1002, not 1 or 0 as the Programmer's
Guide says. I'm guessing that I cannot do what I'm
attempting but I'd like to understand why not. Thanks!
Where was a bug that has already been fixed in the most
recent 5.0.0 builds that was causing it to return a bad
return code. I think you'll find that the create actually
did work.
