Issue:
Upgrading to Endevor V18 and I am getting -
Panel 'C1SD1000' error
Load of panel input exit routine failed.
Panel line where error was detected:
)INEXIT LOAD,ENDDYNPX

I am sure I missed something during the installation, but do not know what.
We are NOT using any Unix Services at this time
Cause:
Program ENDDYNPX is distributed in the Endevor CSIQAUTH library. 
Resolution:
Verify that the TSO logon proc used for accessing Endevor V18 is accessing the V18 CSIQAUTH library.
