In the example in Figure 1, assume that all entry tables are disconnected by the system during address space termination. This means the system reassigns non-system LXs as follows:

• A's non-system LX is reassignable when
  • A terminates or issues LXFRE; and
  • B terminates or issues ETDIS to disconnect from A's LX. If this had been a reusable non-system LX, it would become reassignable regardless of B's action.
• C's non-system LX is reassignable when
  • C terminates or issues LXFRE; and
  • D terminates or issues ETDIS to disconnect from C's LX. If this had been a reusable non-system LX, it would become reassignable regardless of D's action.
