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 cha=
racter 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 conse=
nsus about how this stuff is going to be used, in reality.
