Arrays

Delphi supports two kinds of arrays. One is of a fixed size and has settable lower and upper bounds. We call them static arrays. Others have a lower bound fixed at zero, while the upper bound is variable. In other words, they can grow and shrink. Because of that, they are called dynamic arrays.
