2.3.6 DNC Schedule Operation
In DNC schedule operation, NC programs are prepared on the hard
disk of the personal computer, and data such as the names of programs,
the order of operation, and the number of repeats is stored on a file
called a schedule file beforehand. Then, the NC programs are sent
sequentially as scheduled to the CNC from the personal computer
according to the start signal of the CNC.

storing them must be made readable and writable
