[Example 1] LET 1 10 Assign 10 to variable 1.
CPEQ 1 10 600 Turn ON flag 600 if the content of variable 1
is 10.
600 ADD 2 1 Add 1 to variable 2 if flag 600 is ON.
[Example 2] LET 1 10 Assign 10 to variable 1.
LET 3 10 Assign 10 to variable 3.
CPEQ 1 *3 310 Turn ON output 310 if the content of variable
1 (10) is equal to the content of variable 3.
