SFS doesn't have a choice. It sees the userid CP puts there. But you're right that diag D4 only affects APPC connections made after that point, having no affect on existing connections. So an application that tries to exploit this would have to issue DMSPURWU CSL routine to sever the APPC connection before using Diag D4. Alan Altmark z/VM Development IBM Endicott
