\\ A is a pointer to array

Print Dimension(A, 1) ' for 1 dimension array this is also Length=2
\\ A$( ) is an Array (not a pointer to array)

\\ An array can link to a new name as reference, and can change major type
\\ here A$() get A() so we can read/store numbers and read/store strings in same array
\\ using two names
Link A$() to A()
\\ An array pointer can point to another array
A=A()
Print Dimension(A, 0) ' LBound (0 or 1), here 1 (was 0)
\\ Because B$() is reference of A:
Print Dimension(B$(), 0) ' LBound (0 or 1), here 1 (was 0)
Print B$(1)=A$(1)
Print B$(2)=A$(2)
Print Dimension(C$(), 0) ' LBound (0 or 1), here 0
\\ change base preserve items
Dim Base 1, C$(Dimension(C$(), 1))
Print Dimension(C$(), 0) ' LBound (0 or 1), here 1 (was 0)
Print C$() ' prints Apple Orange
Print Len(C$()) ' Len return all items of an array - can be 0
Dim K(1,1,1,1,1,1) ' Maximum 10 dimensions
Print Len(K()=1 ' True
