Thanks, Jeff.  This could be a good way to manage things.  Unfortunately, I can not guarantee that I can perform a trim operation or that the last character is indeed not being used (for the placement of a nul).  I suppose I could create the wrapper, as you said, and copy the String (1 .. size) to a String (1 .. size + 1) and place a nul in the last character of the target string.  Of course, this does not add a lot of overhead for short strings, but it is a hard real-time system.

It sounds as if I need to get with my people and get a further, clear consensus about how this stuff is going to be used, in reality.
