Just to prevent a possible disappointment, please note that Prime's RPN stack is not "unlimited", but has a hard-coded maximum DEPTH of 128 objects, regardless of available memory. When DEPTH is 128 and a new object is pushed into level 1 of the stack, level 128 gets pushed off the top and is lost. This is very different from stack behavior in the RPL models.

I did not know that. Good to know. That should be plenty. After all, "640K ought to be enough for anybody."
