Installing the ISPF IUI

The IBM® Connect:Direct® IUI is an ISPF dialog. ISPF dialogs have three phases: allocation, invocation, and unallocation. Each of these phases can be done after TSO logon is complete, either outside or inside ISPF. Allocation can also be done through the TSO logon procedure. LIBDEF type ISPLLIB is now supported, so you can invoke the entire dialog from inside ISPF. In previous IBM Connect:Direct for z/OS® releases, the IUI load library had to be allocated outside of ISPF.
