BASE/1133    Bound error: array assign

     Explanation:  When attempting to assign a new value to an array
     element, the subscript specified was greater than the number of elements
     in the array.

     Action:  Correct the program.  The LEN() function can be used to
     determine the number of elements in an array.  The AADD() and ASIZE()
     functions can be used to change the size of an array.
