By choosing [Save IOR Data As...] from the [File] menu, it is possible to open the Save As dialog box and then save the contents of I/O registers in whole to a text file (*.txt) or a CSV file (*.csv) (Regardless of whether you've chosen to show or not show on this panel, the values of all I/O registers are saved.).
When saving to a file, CS+ reloads I/O register values and saves the latest values thus obtained.
However, the I/O registers protected against read are not reloaded. To save the latest content, select [Force Read Value] from the context menu before saving to a file.
