Arrays are lists, indexed by number. So what exactly do you have as the
contents of your arrays - comma separated strings? references to something
else (I doubt this, but . . .)? i.e. how are you storing in @openitems all of
code, type, value, date, ref, ... etc because an array has only an index, and
a value - but that value can be a string, which you can be parsing to get
those things, or a reference to a has, or . . .
