Frank, I've just changed one of our jobs to comment out the SORTWKnn dd statements and use - //DFSPARM DD * OPTION DYNALLOC=(,3) /* The job seems to have done 15 sorts all of which are in main storage ie there are 15 of each of these messages in the output - ICE000I 0 - CONTROL STATEMENTS FOR 5740-SM1, DFSORT REL 14.0 - 15:27 ON MON NOV 14, 2005 - OPTION DYNALLOC=(,3) ICE080I 0 IN MAIN STORAGE SORT yet the dynamic allocation of the SORTWKnn files only occurs 12 times. Is there any reason why the SORTWKnn files should be allocated at all if sort knows it's going to do an IN MAIN sort and if they do need to get allocated why the discrepancy between the number of sorts and the SORTWKnn allocations. Just curious.
