Re: Future of RPG -- RPG400-L

what I dont see mentioned in these posts is that RPG does not have
features that are critical to writing bullet proof modular code.  That
is, it does not have destructors, integrated exception handling,
struct member functions and base classes.

A module has to be able to throw an exception when the inputs are not
what the module expects.   And since a module is going to call other
modules which may throw exceptions, a module has to be able to define
destructor code which will run in the event of an unhandled exception.
That is, code which will shut the module down in an orderly fashion (
close files, release mutex locks, free heap allocations ).
