I would like to solicit some assistance in the use of FSRead.  I have an
application that needs to load data files which are text files full of
numbers.  I am currently using the pascal READLN to load the data one line
at a time, and it is painfully slow.  I have figured out that I can use
FSRead to read huge chunks of data off the disk in one big swallow rather than
a line at a time.  My question is:  how do i know how much memory to allowcate
to the buffer into which the data is placed, and how do i get to the numbers
which are lurking in the buffer, i.e. how do i go to the buffer and ask it
to give me integers or reals or whatever so i can put them into an array?
I would greatly appreciate any assistance.  Thanks.
