Register definitions may saved to, and restored from, disk files as part of ModMaster's configuration (see Saving and restoring the configuration ).

Register definitions can also be saved separately by selecting the File → Export Registers menu item. This displays a dialog that enables you to enter or select the name of the file to save the registers to.

To restore the registers from a file, use the File → Import Registers menu item. This displays a dialog that enables you to enter or select the name of the file to restore the registers from. If ModMaster is "running" (i.e. the Run button is depressed), you will have to click the Run button again before you can load the registers.

Loading from a file will add new register definitions and replace existing register definitions, but will not delete any register definitions. If you want to totally replace the the set of register definitions you should delete all the register definitions (using the Delete All button in the Register Table page) before importing the new definitions.

Export Registers saves the register definitions in CSV format, and Import Registers expects the file it reads to be in CSV format. The CSV format is described in the CSV file format appendix.
