System and computer-readable storage medium Technical Field The present disclosure relates to systems and computer-readable storage media. Background Conventionally, a spatial error of a processing machine is measured. (for example, patent document 1). Based on the measurement result of the spatial error, a correction value of the spatial error is set in the control device. Prior art literature Patent literature Japanese patent application laid-open No. 2016-64497 Disclosure of Invention Problems to be solved by the invention However, whether or not the correction value is correctly set in the control device based on the measurement result of the spatial error is confirmed by the operator again measuring the spatial error with the measuring instrument. Such a confirmation job is a large burden on the operator. Therefore, there is a need for a technique in which an operator can confirm whether or not a correction value is correctly set in a control device without performing measurement of a spatial error again.
