Thanks, that looks like exactly what I need.  I wonder if someone could
put a reference to this array utility package in the manual, chapter 8, on
arrays.

Maybe something like this: 
For more complex work with arrays, see Massimo Dal Zotto's contrib package
'array_iterator'.  This loadable module "...defines a new class of
functions which take an array and a scalar value, iterate a scalar
operator over the elements of the array and the value, and compute a
result as the logical OR or AND of the iteration results."
