2. A numerical control device as claimed in claim 1, wherein said language discriminating means in said control means comprises means for determining whether high level language processing is being effected, and for determining whether an inputted machining program comprises a high level language start delimiter instruction and for determining whether said inputted machine program comprises a high level language end delimiter instruction, said high level language start and end delimiter instructions bracketing a set of a selected number of said higher level language instructions in said flow of said inputted machining program and wherein said NC and high level language interpreting means do not interpret nor process said high level language start and end delimiter instructions.
