Try this one:
M = ReadList["Macintosh HD:Mathematica 3.0 Files:fish:aqc.grd",
Number, RecordLists -> True];
It just reads every number into a list, making a new sublist for each
new line in the file. This works for a matrix of any dimensions. After
reading, check it's size with
Dimensions[M]
I hope this helps.
