           MK31B reads the ASCII version of the phase file created by RD31 and 
        creates a binary version. Both "full" or "short" files can be input, 
        and the program automatically determines which type was provided. See 
        RD31 section for details on the files. The program is interactive and 
        prompts only for the names of the input and output files.
