Hi, 


The problem I present today is related to the coexistence between big-endian and little-endian application data.

I have found a way that structures (records) are stored in memory according to one criterion or another (big-endian or little-endian).

Assuming that 'Date' is a structure type, I can use the following statements to indicate that I want them to be stored in memory as big-endian:

   for Date'Bit_Order use System.High_Order_First;
   for Date'Scalar_Storage_Order use System.High_Order_First;


My question appears when I have a simple type, such as an enumerated or an integer that occupies more than one byte and I need to instruct the compiler to store it in memory as a big-endian. Like this example:

   type Colour is (BLACK,YELLOW,WHITE,RED);  
   for Colour'SIZE use 32;

Is there any analogous way of doing this as in the case of compound types?


Thank you so much.
