I have written such code, since there is no other "hook" area to get control
early enough in the IPL process. I know that placing the SSI routine first
guarantees that other SSI stuff will wait until it is done. I have inserted
other system hooks, issued an ASCRE's and waited for the initialization exit
to complete before allowing the next SSI routine to get control.

Now, if IBM wishes to add some new - PARMLIB specified - early IPL exit I
would go along with it.

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
