Also, you forgot the RETURN VALUE on your RPG prototype. Your C
prototype returns an int -- but the RPG side shows no return value.
Change it to have 10i 0 as a return value, otherwise those 4 bytes that
are returned could possibly be overwriting memory used for something
else -- and that might be hard to catch in testing, but could result in
the dreaded "unexpected results" in production.


Scott,

I can't believe I'm going to do this, but...

Are you sure about that? Is it just the fact that the prototype
doesn't declare the return value that could cause the problem? The
return value doesn't have to be used though right?

Thanks!
Charles
