Hello everyone! I am having a problem that I would love some help 
with.

Essentially I was given a Visual Basic program that dumps a binary 
configuration file with all of the variables in a set.  The variables 
are each 32 bit floats, with the first 16 bits being the integer part 
and the second 16 bits being a representation of the fraction (I'm not 
sure if this is stanard - but its just how VB dumps the data). The 
binary dump is basically a copy of the way VB stores the data in 
memory.  I need to be able to use this data in ada.  There is a C 
counterpart to this that makes use of a 'union' to grab the data 1 
byte (8 bits) at a time, put them into a char array of size 4, then 
use a 32 bit float to reference the data.  Is there somehow I can do 
this in ada as well?

Basically I need to be able to read in the binary data byte by byte 
but store it into a 32 bit Float.  The C union example above uses the 
same memory address for the Float as it does for the size 4 char 
array. I don't even know if the VB dump will correspond with the way 
ada handles floats or not, but I'll worry about that later.

I am also using Matlab/Simulink if that provides any additional tools 
to use for debugging.

Thank you for any help,
Blaine
