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
