An unsubscripted array reference on the left hand side of an assignment is converted to a vector (see above). This means that the result of the assignment depends on whether the vector is ``big-endian'' or ``little-endian''. For example, if:
x : array 0..1 of boolean;
then
x := [1,0];
is equivalent to
[x[0],x[1]] := [1,0];
which is equivalent to
x[0] := 1;
x[1] := 0;
On the other hand, if:
x : array 1..0 of boolean;
then
x := [1,0];
is equivalent to
[x[1],x[0]] := [1,0];
which is equivalent to
x[1] := 1;
x[0] := 0;
