JVT	JUMP IF OVERFLOW-TRAP FLAG IS SET.
	Tests the overflow-trap flag. If the flag is clear,									JVT	cadd
	control passes to the next sequential
										(11011100) (disp)
	instruction. If the overflow-trap flag is set, this
	instruction clears the flag and adds to the
	program counter the offset between the end									NOTE: The displacement (disp) is sign-
	of this instruction and the target label,
											extended to 24 bits.
	effecting the jump. The offset must be in
	range of –128 to +127.

LCALL	LONG CALL. Pushes the contents of the
	program counter (the return address) onto									LCALL	cadd
	the stack, then adds to the program counter
										(11101111) (disp-low) (disp-high)
	the offset between the end of this instruction
	and the target label, effecting the call. The
	offset must be in the range of –32,768 to									NOTE:	The displacement (disp) is sign-
	+32,767.
