DSNUEXIT user-defined variables for REORG PLUS

The DSNUEXIT user exit returns user-defined variables to REORG PLUS.

You can use these variables with the DSNPAT installation or command option to construct data set name patterns. REORG PLUS uses these patterns and the values returned for any user-defined variables to create data set names during dynamic data set allocation. You can also use these variables with the SPILDSNP installation option or SPILLDSNPAT command option to construct patterns for data set name prefixes. REORG PLUS uses these patterns and the values returned for any user-defined variables to create the data set name prefix for the spill data sets used when running a SHRLEVEL CHANGE reorganization.
