Connecting to the Bloomberg Data Server

This example shows how to use the bloomberg function to connect to the Bloomberg data server.

The syntax for this function is:

Connect = bloomberg

This function returns a Bloomberg connection object c:

c =
 
    connection: 84554360
     ipaddress: '123.456.54.123'
          port: 8194

The connection field within the object c contains the Bloomberg connection handle that the bloomberg function uses to process future data requests.
