hi

L	P#8.7	Load the value of the pointer into accumulator 1.
T	MD2	Transfer the pointer to MD2.
A	I [MD2]	Query the signal state at input bit I 8.7 and
=	Q [MD2]	assign the signal state to output bit Q 8.7.

L	P#8.7	Load the value of the pointer into accumulator 1.
LAR1		Load the pointer from accumulator 1 into AR1.
A	I [AR1, P#0.0]	Query the signal state at input bit I 8.7 and
=	Q [AR1, P#1.1]	assign the signal state to output bit Q 10.0.

L	P# I8.7	Load the value of the pointer and the area identification in accumulator 1.
LAR1		Load memory area I and the address 8.7 into AR1.
L	P# Q8.7	Load the value of the pointer and the area identification in accumulator 1.
LAR2		Load memory area Q and the address 8.7 into AR2.
A	[AR1, P#0.0]	Query the signal state at input bit I 8.7 and
=	[AR2, P#1.1]	assign the signal state to output bit Q 10.0.
