Assigns the execution focus to the specified virtual machine. Uses Flags.

• Clears the carry flag if the execution focus is assigned; otherwise, sets the carry flag.

VMHandle

Handle of the virtual machine to receive the execution focus.

When a virtual machine receives the execution focus, the system suspends all other virtual machines except the system virtual machine and background virtual machines.

Only the system virtual machine can assign the execution focus to other virtual machines; a non-system virtual machine can only assign the execution focus to itself.
