COMP→

Description:	Composite out command: This is equivalent to the RPL LIST→ command, but it also works on
	Program and Symbolic objects.
Input/Output:
		Level 1/Argument 1		Leveln+1/Item1 ...	Level2/Itemn	Level1/Itemn+1

Library Object	→	¤n
“string”	→	¤n

Example: "D9D20003621113" CRC returns ¤ 8B63h.
