this is the data which is saved by the name winspd.txt. I used ASCII
macros to read and when tried to reverse structure data, it gave error
as i mentioned in my last post, i.e.,
> array = data
> array = Reverse(array, 1)
> lat = Reverse(data.lat)
> % ROTATE: Struct expression not allowed in this context: A.
> % Error occurred at: REVERSE

It is hard to tell exactly what you are doing,
but it sounds like you probably got a structure
returned from a function, and that the structure
contains your wind speed and location data. If
that is the case, you need something like this.
struct = ASCII_MACRO()
windsp = struct.data
lat = struct.lat
lon = struct.lon
Then, you probably want to reverse your windsp and lat
variables in the Y direction if you are planning to put
these on a map.
windsp = Reverse(windsp, 2)
lat = Reverse(lat, 2)
Cheers,
David

maybe you data is not structure one! if it is, have you tried:
Data=Data.(0)
Cheers,
