Well, that explains why the parm doesn't get us anything. It may also explain why the directory cache is completely ineffective, especially as *that* is also set to the IBM default value, which is 2GB. What really galls me is that init&tuna reference doesn't even mention that! And nonSMS managed PDSEs have been around a long time, too! So we are supposed to just *know* when it's specified in IGDSMSxx, it doesn't apply to PDSEs, only to *sms-managed* PDSEs. Good thing it's Friday.
