From: "Dennis Debro" > Is it possible to have a DLI point to another DLL? From reading this it says it's limited to a scan line unless I'm reading it wrong. It would be nice to have a DLI spin off to another DLL so the screen could be split vertically with two "kernels" running. Nope, to point to a different DLL you'd have to change the DPPL/H registers and those only get read at the start of every screen. For what you can use the DLI for have a look back in the list archives (11-2003). But maybe if you can explain the effect you are trying to accomplish we can come up with some suggestions.
