Bruce,
You need to Evaluate the left hand side, and generally also Clear A in
advance if you ever reevaluate.
Clear[A];
Evaluate[Array[A, 3]] = {1, 2, 3};
{A[1], A[2], A[3]}
{1, 2, 3}

The command:
{A[1], A[2], A[3]} = {1, 2, 3}
assigns a value to each A-variable. However, the command:
Array[A,3] = {1,2,3}
generates an error message.
What is the difference between the two lines?
Thankx.
Bruce
