This will write out a single spectrum and its data to disk.

‘Spectrum/File name?’ asks you for the spectrum name and the file name to write the spectrum out to. The two names should be separated by the '/' symbol or the program will assume that the input is only the spectrum name.

If you neglect to give the program a file name on the first prompt, it will prompt the user again if no file name is yet connected to that spectrum. (A file name is connected by either loading the spectrum in or writing it out to that file).
