Hi,
Why not just catch the standard c++ exception and show the "what"?
Currently I´m using the code below in all exported methods but I think it
would be easier if the rexx itself does the "catch" and show the exception.
Is there a better way and I don´t know it?
try
{
(...)
}
catch(std::exception &e)
{
context->RaiseException1(Rexx_Error_Application_error,context->NewStringFromAsciiz(e.what()));
}
