I am working with large datasets that I would prefer to store as binary
data rather than ASCII.  These files could be, for example, single- or
double-precision numbers.  What is the most efficient way of handling
input and output of such datafiles in Mma?  I've considered writing an
external translator to read the data and pipe it to Mma in ASCII, but I
wonder if it is possible to access binary data in a file directly.
