I am not sure you have a problem.you
When you issued the FREE SPACE command against the PARMLIB data set,
only force it to go back to the primary space if it could. Forinstance, if
your SYS1.PARMLIB had CYL 1,1 and had 5 extents, then the free wouldwould
have left it CYL 1,1 but maybe now down to 1 extent. It is not anissue
unless something is looking for a member at the exact TTR location itwas
before.in
I would first issue a D GRS,RES=(*,SYS1.PARMLIB) and see what has it
current allocation (yes there are other methods).the FREE
Next I would review the allocation (option 3.2 or 3.4) and see what
did.or
You maybe okay. The free does not reduce your secondary allocations
remove what was there. It is more like a Compress.
F - Free unused space - not destroy data set.

Lizette,
This is not true. FREE frees all space behind the last used track/cyl
and it does not change the allocation amounts. It does not touch the
data, either by reorganize or compress.
In the case of CYL 1,1 and 5 extents there is nothing to free, because
all extents have been taken to write data into. If it was compressed and
the last data would be in extent 3, the last 2 cylinders will be freed.
If the dataset is CYL 5,5 and has 5 extents, the 5 cylinders in the last
extent will probably not used all and the unused cylinders will be
freed.
Kees.
