Containers are always dimensioned as globals. I have a question about their
memory requirements. Containers may hold several gigabytes of information.
Is the amount of memory allocated, set at some very large value when a
container is dimensioned, or is the memory allocation dynamic? In other
words, is the amount of memory allocated just one byte when a container is
"empty"? If a container holds, say just one ASCII character, is the memory
allocated to it then 3 bytes?
