With Jon Peck's help I have gotten MODIFY OUTPUT working.

The first thing in the fix was  that I uninstalled the SPSS statistics Python Essentials and reinstalled it.  The syntax then worked. It was very fast.

I  learned that MODIFY OUTPUT works on .spv files that have been read back in (unlike MODIFY TABLES which I mentioned in an earlier post this morning).

I learned that if you want to delete whole groups of itemtypes you can set them as hidden BEFORE the run by
<edit> <options> <viewer>
OR
you can hide or make visible very specific index entries by clicking on the little icon in the index until it says
 "hidden" or "visible" in the bar at the bottom left of the output screen.  The last segment in the example syntax  will delete only hidden index entries.

There is syntax below that demonstrates some output clean up syntax.  I suggest that you highlight segments and run them one at a time to see what they do.

I confirm the SPSS MODIFY OUTPUT is reasonably fast. I have just tested it on
a 3,7 MB spv output file - btw generated when I still had v18 installed -
using a MacBook Pro (Intel 2.4 Ghz, 4 GB RAM) and V19.0.0.1 and I have got
it modified in 30 seconds.

So something must be wrong with your settings, can you easily run other
extension commands?
