PROBLEM:  I am using Standard ML (New Jersey), Version 0.66 and I am trying
to use the Array function "length" to get the length of an array.  I have
defined my array using arrayoflist:

	eg.	val My_Array = arrayoflist ["Hi","My","Name","Is","Bob"];

	Now I want to use "length My_Array" to return the integer 5.

The reference manual I am using, says that this can be done and that the
function length is one that takes an array and returns an int.

However, this gives me an error when I try it in my version of SML and when
I type "length;" it tells me that length accepts a list and returns an int,

	eg.	length My_List;  returns the length of the list, My_List.

	I have tested this and this is the case.

The discrepancy between my reference manual and my version of SML is not the
major concern here, what I really want to know is:  Is there a way to get
the length of an array in the version of SML I am using.  This is important
to my application because I have a statement that says My_Array sub i where
i is begin incremented; hence, once i is out of range for the array, I don't
want the function to continue executing.

Any help would be greatly appreciated.
