Bruce,

I attempted using the DELETE but it just took too long! In the CL I have a
RUNSQLSTM that drops the indexes and another to rebuild them at the end. I
just can not figure out why the INSERTs went south after the CLRPFM, the
program was running fine but it was doing about 1 row every 3 or seconds,
ran from the 26th till Monday. What is really surprising is that ops gave me
a get outa jail free card on that! :-)

There is no real reason that you could not, unless there are constraints on
the file. Then the clear may fail.

You said no DDL, so use DML... delete * from table
Again, if the constraints are honored (or non-existant) this will work. I
have seen tables with foreign key constraints that have rejected the clear,
but taken the delete *, but I have not investigated them further.

Maybe suspending the constraints, clearing and then reloading and reapplying
the constraints would work in that situation if you can't use the delete for
some reason.
