Are there separate pools of page data sets for above the bar and below the bar? Are there separate limits for total (system-wide) virtual storage in use below the bar and above the bar? Are the costs of resources (page and segment tables and other overhead) for above the bar and below the bar different? Unless the answer to at least one of these (or any similar question) is "Yes," effect of giving a gazillion bytes is the same above the bar as below.
