CALL

CALL is a non-motion instruction that causes the robot to halt progression of its current running program, throw all of the currently-in-use data about that program into the processor's stack, and start another program.

SELECT	Variable	Math	Variable	Action	Destination
SELECT	R[1]	=	1	Call	Program1
		=	2	Call	Program2
		=	1	Call	Program3
	Else			JMP	LBL2

Call instructions are special in that they're intended to return once they have been completed.
