Binary I/O for Newbie

[tjb]

All,

I am just starting to learn D.  I am an economist - not a 
programmer, so I appreciate your patience with lack of knowledge.

I have some financial data in a binary file that I would like to 
process. In C++ I have the data in a structure like this:

struct TaqIdx {
  char symbol[10];
  int tdate;
  int begrec;
  int endrec;
}

And I use an ifstream to cast the data to the structure in read.  
I'm struggling to get a handle on I/O in D.  Can you give some 
pointers?  Thanks so much!
