You must name the logon post-display exit IKJEFLN2. Link-edit IKJEFLN2 as a separate load module. You can link-edit the exit in a separate, authorized load library that is exclusively for TSO/E exits or in an existing library containing other routines. The exit can reside in:

• The link pack area (LPA)
• LNKLST

For more information about using the LPA or LNKLST, see Installing the standard-format exits.
