Thanks for the offer. The SORT never worked due to, uh, never mind as I don't want to cast aspersions. And, in any case, the SORT was replaced by a MERGE because the input was from two files which were already sorted in the correct sequence. The reason I asked was that this is likely going to result in a demand that the default number of SORTWKnn DDs be increased from 32 to some larger number. Our programmers do NOT want to take responsibility for calculating SORTWKnn space, even for extreme cases. I guess that I can understand that, but I'm becoming depressed by the decreasing level of knowledge and expertise shown in our line of work. We are not longer "craftsmen" but "assembly line workers".
