All of these entry points are in pages 0, 1 and 2. Are any of these exclusive to the CX, or are all of the CX entry points higher up, in pages 3 and 5? I'm interested in knowing where the code resides which is CX-specific but which can't be added to a C or CV with the Time and X functions modules. Would that be page 3?

For the most part those entry points are common to the CX as well. There are some changes made to the CX OS to connect with pages #3 and #5 - this one has two banks to accommodate not only the time module but also additional X-Functions code not present in the XF/M modules.

So yes, as you suspected that's where the code is - which explains why the library#4 concept works on the CX since all the addresses have a fixed location and thus the system calls need not to worry about XFM module locations at all.
