Hey i need to use a function called read_wind_mfi.pro

It is from WInd_3dp libraries made for analysing data from Wind spacecraft by Dr. Lynn Wilson of Nasa.

The read_wind_mfi.pro is used to load the magnetic field data which I have stored in my directories.

;+
;*********************************************************** ******************************
;
; FUNCTION : read_wind_mfi.pro
; PURPOSE : Reads in 3-second Magnetic Field Instrument (MFI) data from
; the Wind spacecraft and returns a structure composed of the
; the GSE magnetic field, its magnitude, and the times
; associated with the data in seconds of day (default tag is in
; unix time).
;
; CALLS:
; time_range_define.pro
; read_cdf.pro
; epoch2unix.pro
; fix_bfield_data.pro
;
; REQUIRES:
; 1) UMN Modified Wind/3DP IDL Libraries
; 2) Wind 3s CDF files from CDAWeb
; e.g. 'wi_h0_mfi_YYYYMMDD.cdf'
;
; INPUT:
; NA
;
; KEYWORDS:
; DATE : [string] 'MMDDYY' [MM=month, DD=day, YY=year]
; TRANGE : [Double] 2 element array specifying the range over
; which to get data structures [Unix time]
;*********************************************************** ********************

This is the notes given in the read_wind_mfi.pro and it should be called by

IDL> test = read_wind_mfi([arguments],KEYWORDS=[keywords])

this. Now I need to know what to put in the place of arguments and keywords ?

Can you please provide me an example of it , so i could just change the value and put it on IDL. ?
