The key is written with the dataset so it will still be uncompressible.

Thanks....Rick

Subject: Backing out of COMPRESS(TAILORED)?

I just learned about, and turned on, COMPRESS(TAILORED) in SMS. Things
were working OK, then we had a user job abend because the region size
was too small (213-ED abend, with 378 abend also showing); trying to
browse the dataset after that got 213-E0.  We were able to recover this
job and change the region size, but it did raise a question:

Once I have turned on tailored compression, if I wanted to switch back
to the generic version, what would happen to any datasets that were
compressed with tailored compression? Would I have to identify them
somehow and uncompress them before turning the option off?
