FWIW I'm knee-deep wading in the Advantage/CCD MCODE investigating a way to adapt the Matrices/MSYS/DET code to use the CL Y-registers instead... conceptually quite simple but the code structures make it rather tricky. Stay tuned.

Not easy but after a couple of days reverse-engineering the original (and largely convoluted!) MCODE progress has been made: behold the Y-Advantage Module, which uses the CL Y-registers in full functionality. Just use the control character "Y" (instead of the original "R") and the matrix will be created/used from the Expanded registers area, from YR000 to YR1023.

Testing is holding up well so far, including the major operations (MDET, MINV, MSYS).
The "Y" control character replaces the same code used before with "R". I don;t know if both can be enabled simultaneously, so further investigation is in order.

To be continued.
