XINTELOK XINTELOK saves the various types of external interrupts that are presented to the virtual
machine. If multiple external interrupt conditions are simultaneously [resented, as
indicated by values presented in the block, code exists for handling the interruFts in
their defined hierarchical order. The VMPXINT field of the VMBLeK points to XINTBLOK. o
