Note that a colon is used to separate the lower bound from the upper bound in an array declaration. It is possible to declare empty arrays, where the upper bound is equal to the lower bound - 1.
The short-hand form "array A,B,C(1:100),D,E(1:10)" is equivalent to "array A(1:100),
B(1:100),C(1:100),D(1:10),E(1:10)".
All elements of an array are initialized according to the same rules as hold for simple variables.
