It looks like Cibi Raj has given all the documentation that was available, but needs a hand to connect the dots. If they had added an EXAMPLE section to the documentation, it might look like this:
; EXAMPLE
; result = read_wind_mfi(DATE='123199', TRANGE=[startTime, endTime])
; (where startTime and endTime are numbers in "Unix time")
; (https://en.wikipedia.org/wiki/Unix_time)
Don't give up hope! I think you first need to know the basics of IDL procedure and function calling. This page, describing how IDL routines are documented, may give some helpful examples:
http://www.exelisvis.com/docs/idl_syntax.html
Can anyone offer a link to a better "orientation" for someone who is thrown into the waters of IDL, perhaps as a first-time programmer without access to a mentor or even a good book? I will point out David's fine book (in PDF form), for those who have the option of buying it:
