... function.

I cannot see a reason for directly allocating another MStack other than Dispatch, since the matrix functions push their results onto Dispatch. Maybe someone with a parallel processor would want several independent stacks, but the rest of the program would have to be rewritten. The vmm system would need to be scrapped too. It's clear YAMP is a PC program

... (Tran(X)*X).DispalayMat();.

By the way, just what is this, a statement or a function call?
