41CL Maximum registers for DATA/PROGS storage

[Podalirius]

Hi, I use a hp 50g with the HP-41X emulator by Hrast Programmer.
This emulator give me over 3000 registers: I use SIZE 900.
More of this I have installed the W&W RAMBOX emulation, that store
programs and permits to execute them from rambox page.
I don't understand from 41CL manuals if exits a possibility to store
programs in a page and execute from this page and if in 41CL
the rambox use hp 41 standard ports or pages.
Thank you very much!!!
