[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 2 Assign 2 to variable 1.
LET 2 10 Assign 10 to variable 2.
LET 3 10 Assign 10 to variable 3.
CPNE *1 *3 310 Turn ON output 310 if the variable that
corresponds to the content of variable 1,
or 2, is not equal to the content of
