The fmode command allows you to return to the fitting mode, when the program is in one of the C-calculator or plotting modes. The fitting mode, is the main mode of the program. The two other modes are the C-calculator mode, accessed by the cmode command, and the plotting mode, accessed by the pmode command. When used interactively, ˆ D returns to the fitting mode from either of the C-calculator mode or from the plotting mode. It is not an error to call fmode from the fitting mode. A warning message will be given though.
