// Purpose: The class Array2 represents unidimensional arrays
// of fixed size known at run time.
// The range of the index is user defined.
// An array1 can be constructed with a "C array".
// This functionality is useful to call methods expecting
// an Array1. It allows to carry the bounds inside the arrays.
// Examples: Item tab[100]; // An example with a C array
// Array1OfItem ttab (tab[0],1,100);
// Array1OfItem tttab (ttab(10),10,20); // a slice of ttab
// If you want to reindex an array from 1 to Length do :
// Array1 tab1(tab(tab.Lower()),1,tab.Length());
// Warning: Programs client of such a class must be independant
// of the range of the first element. Then, a C++ for
// loop must be written like this
// for (i = A.Lower(); i <= A.Upper(); i++)
// Changes: In comparison to TCollection the flag isAllocated was
// renamed into myDeletable (alike in the Array2). For naming
// compatibility the method IsAllocated remained in class along
// with IsDeletable.
