Now in the READ at runtime there is a loop specification that is initialized to allow the read process to loop through these elements of an array. This works fine elsewhere, so I suspect, based = on what you see here, that this loopspec is not getting initialized correctly meaning the array descriptor is uninitialized or otherwize corrupted. It i= s a bit late for me to look at this tonight, but as I get time I will examine w= here we set the loop spec and where it comes from.=
