Rewrite data writing to file
Fmt() uses by default truncation to conver double arguments to their text
representation. Rounding must be used. Rewrite using standard C functions to
get rid of this problem (and probably make it more efficient). Extend to handle
arbitrary number of channels and to report errors on opening the data files.
