No.										(∝ s)
114	Device/register	− [ SET		A ]−				If A is a device:
	set							Sets device A to ON.	2	4.2	196
								If A is a register:
								Stores HFFFF in register A.
115	Device/register	− [ RST		A ]−				If A is a device:
	reset							Resets device A to OFF.	2	4.2	197
								If A is a register:
								Stores 0 in register A.
118	Set carry	− [ SETC ]−						Sets the carry flag to ON.	1	4.2	198
119	Reset carry	− [ RSTC ]−						Resets the carry flag to OFF.	1	4.2	199
120	Encode	− [ A ENC			(n)		B ]−	Finds the uppermost ON bit
								position in the bit file of size 2n	4	57.0 -	200
								bits starting with register A, and		141.4
								stores it in B.
121	Decode	− [ A DEC			(n)		B ]−	In the bit file of size 2n bits
								starting with register B, sets ON		69.5 -
								the bit position indicated by	4		201
										99.1
								lower n bits of A, and resets
								OFF all other bits.
122	Bit count	− [ A BC B ]−						Counts the number of ON bits	3		202
								of A and stores it in B.
147	Flip-flop	S	F/F			Q		Sets ON device A when set
		R	A					input (S) is ON, and resets OFF
									2	26.7	215
								device A when reset input (R) is
								ON.
								(Reset takes priority)
149	Up-down	U	U/D			Q		While enable input (E) is ON,
	counter	C						counts up or down the number
		E		A				of cycles the count input (C)
								comes ON, depending on the	2	30.1	216
								up/down select input (U).
								Up when U is ON, down when U
								is OFF.
