- setVariable is used to store an array
- this is stored to a variable with getVariable
- set command is used to change the first element
- substraction is used to remove the first element
- getVariable is used again, it's different from the first one
Note that the 2nd getVariable returns [-1, "2nd"], so the substraction didn't do anything to the variable in variable space of the logic.
