Looks that way.

Sure - the purge program looks at the closing data and backs out the
save window. Unless the save window is > 4 years the purge date is
greater than today!

How about using a query (similar to my previous post) to build a file
of the restored ITH without the records for deleted IIM.  This will be
easier than the one in my previous post.  You can use SQL if you are a
masochist -- CREATE TABLE XXX AS SELECT * from RESTORE/ITH ....

I have one if you want.  Minor adjustment required because of date
formats (yymmdd vs cyymmdd).  Contact me off line if you want it.

The old way is a a poor solution.  If you are concerned about this
happening again, submit another request to the list and you will get a
ton of alternative selections.  My suggestion .. before monthend, copy
key files into a temp library, get them onto the monthend tape backup,
then delete the temp library.
