SUB (Subtraction)
[Function] Subtracts the data in Operand 2 from the variable in Operand 1, then stores this in the variable in Operand 1.
Subtracts the variable in Operand 2 from the contents of the variable in Operand 1 and stores this in the variable
in Operand 1. If there is a post instruction (flag, output port), it turns ON when the computation result is zero.
[Example] SUB 1 10
If the content of variable 1 in Operand 1 is 20, then 20 (content of variable 1 in Operand 1) - 10 (data in
Operand 2) = 10, and after the command is executed, the content of variable 1 becomes 10.
SUB 1 *2
If variable 1 in Operand 1 is 20 and variable *2 in Operand 2 is 10, then 20 (content of variable 1 in
Operand 1) - 10 (contents of variable *2 in Operand 2) = 10, and after the command is executed, the
content of variable 1 becomes 10.

[Function] Multiplies the data in Operand 2 by the variable in Operand 1, then stores this in the variable in Operand 1.
Multiplies the variable in Operand 2 by the contents of the variable in Operand 1 and stores this in the variable
in Operand 1. If there is a post instruction (flag, output port), it turns ON when the computation result is zero.
[Example] MULT 1 10
If the content of variable 1 in Operand 1 is 10, then 10 (content of variable 1 in Operand 1) x 10 (data in
Operand 2) = 100, and after the command is executed, the content of variable 1 becomes 100.
MULT 1 *2
If variable 1 in Operand 1 and variable *2 in Operand 2 both contain 10, then 10 (content of variable 1
in Operand 1) x 10 (contents of variable *2 in Operand 2) = 100, and after the command is executed, the
content of variable 1 becomes 100.
