The instruction is not to be confused with the electronic device or the alphabetic rule and may or may not be computerised. The alphabetic set of directions is the ideality of the embodiment of the text-manipulation that instantiates the alphabetic form of the score. 'Instruction' is not viewed as matching the program per se or the notational direction in entirety. The executable set of directions is the embodiment of the personification of the direction that realizes the performance form of the script if it is to write.
The instruction is not thought commensurate with the computer program or the executable score and is language independent. The Instruction is the set of directions that is the encapsulation of the writing machine or the performance instruction.
