Newby. From IBM System/3S0 Operating System: Programmer's Guide to
Debugging OS Release 21.7, GC28-6670-6:
FQE: The FQE describes a free area within a set of 2K blocks
described by a DQE. It occupies the first eight bytes of that
free area. Since the FQE is within the subpool, it has the
same protect. key as the task active within that subpool.
Extreme care should be exercised to see that FQEs are not
destroyed by the problem program. If an FQE is destroyed, the
free space that it describes is lost to the system and cannot
be assigned through a GETMAIN.
>The data areas book says that FQEs are in SP 245 or 255, SQA or
>LSQA.
That may be true for contemporary systems, but it was not always thus.
