sockets/binary data

>Hello - I am a new user of Dolphin Smalltalk which I am enjoying
>immensely.  As a learning exercise, I am trying to use Dolphin to
>develop a test client for a distributed messaging platform.  The
>platform utilizes a proprietary TCP based binary messaging protocol.
>There are various datatypes in the protocol including the IEEE double
>format which is used to represent C doubles.  My only question is how
>do I create an object/value for such a double within Dolphin after I
>have read a sequence of bytes from a socket?  I have studied the
>external interfacing portion of the documentation but as a beginner I
>can't quite pull together how to apply these concepts to my problem...

>Any pointers to the appropriate documentation or functionality within
