Error description
DTU 4.6 always allocates EQARESDS and EQATY2DS DDs if dsnames for them are provided, but it uses and deallocates the datasets only if class selection changes. Exiting DTU 4.6 without changing the class list leaves the DDs allocated, causing FILE IN USE messages on the next use of 4.6 in the same TSO session.
Local fix
Issue DDLIST and release the DS in there.
