Abstract
A numerical control unit (NCU) uses character codes to communicate with an external input/output apparatus. Further, internal NCU data is stored in an array format corresponding to a display format. Further, while one set of data is being executed by the NCU, another set may be corrected by the user. Further, program data may be specified as variables rather than actual numerical values. Still further, memo data is provided to describe each piece of data. Finally, input program data is directly sent to a buffer where it is used to control a machining operation.
