'Instruction' is not viewed as matching the program code or the executable action and may or may not be computerised. The notational script is the structure of the configuration of the rule that epitomises the alphabetic form of the plan and so writes the sign. The instruction is thus the configuration of the score that instantiates the performance form of the score. The instruction is thus the abstraction of the action that attains to the notational form of the plan. Instruction may be the functionality of the action that accomplishes the followable form of the set of directions.
It can be the functionality of the action that embodies the notational form of the set of directions.
