The documentation reads: Method ReadInt() Returns: The read value Description: Read an int (four bytes) from the stream Information: If a value could not be read (possibly due to end of file), a TStreamReadException is thrown. ____ If (SocketReadAvail(socket) >= 4) Then ________ intPacket = ReadInt(stream) ____ End If Does this still apply if the application is run from a 64bit system? Should I be using SizeOf(int) ? What if I have a C++ Winsock host running on a 64bit system, sending a 8bit integer? What will happen to my client on a 32bit system? Some clarification would be awesome! Thanks in advance.

I'm not sure what C++ would use, but data types in Max are always the same, regardless of processor architecture.

ok, that clears a bunch up. Last thing to find out is if I should be checking the socketstream for 4 bytes or 8 bytes.

bm builds no 64bit as such there is no problem, it will always be 32bit

BlitzMax ints are 32 bits, longs 64 and shorts 16. If you are not sure, you can always call len(variable) to know its size (on a non-class variable). --> This does not work. Use SizeOf instead.
