How can you tell where you code lives or how much you can have?  

The biggest limited of OpenVMS (which traces its way back to Macro) is that the stack is in 32-bit space.  I don't think there is ANY way to tell the image activator to allocate it anywhere else.  And if you do can, you won't get very far.
