41CL Quiz: Determinant of 30x30 anti-Identity matrix

Obviously the bottleneck here is the FOCAL program that calculates the determinant. I'm toying with the idea of modifying the MCODE-based functions in the Advantage to also support the Y-registers, but it's a tall order...

Saludos y buen finde.
ÁM.

Gene: My mind went to the Y-registers applications rom right away (rom ID 21). The PPC matrix functions and the JMB are in there in FOCAL. Will love to see what the YRRM program does at 50X on this. MUCH slower than Valentin's solution though. :-)
