Yes, you can alter an existing DATACLAS to have the Extended Addressing attribute. HOWEVER! This does not affect _any_ existing data sets. It only affect _NEW_ allocations. Every DATACLAS we have in our house has Extended Addressing set. We have not noticed any impact from doing this. We did this because we had programmers use the non-Extended DATACLAS for VSAM data sets, then get upset 8 months later when their "small" data set had to exceed 4Gig. When told to unload/delete/define/reload, they got quite incensed
