FFT

        ANALYSE\FFT [/REMOVE [wmin wmax]]
                    [[s1 e1] [s2 e2] ... [s10 e10] /KILL]
                    [/INDEX] [/OBS] [/NOCURS]

    FFT  computes a Fourier Transform and plots it. It acts either on a sin-
    gle spectrum (from the R buffer) or on the INDEX. The  default  behavior
    is  defined with SET ACTION, but can always be ignored with /OBS or /IN-
    DEX. Identically, the option /NOCURS overrides the default cursor. /KILL
    allows  to  linearly  interpolate the fourier transform, either interac-
    tively or by supplying values. The /REMOVE  option  indicates  that  the
    fourier transform is to be computed from a spectrum linearly interpolat-
    ed in some intervals (specified or taken from the last fitted profiles).

    If  the  action is applied on the R buffer, the result (including /KILL,
    if any) of the FFT is available in the variables R%FFT%X and R%FFT%Y.
