Determining dynamically allocated data set names (RVP)
The utility provides various methods for determining and controlling the data set name to be used for an output copy:
Provide a model data set name that contains substitution variables and literal values. The utility resolves these substitution variables and substitutes current values as it dynamically allocates the output data set during execution. This method is available only if you use dynamic allocation models.
Provide a data set name prefix with the PREF or ICPREF keyword. The utility uses this prefix according to standard rules to build the data set name as it allocates the data set dynamically during the run. This method is available if you use dynamic allocation models or dynamic allocation keywords on function or GROUP control statements.
Use the Data Set Name user exit. This method is available if you use dynamic allocation models (and specify the PREF keyword) or dynamic allocation keywords on function or GROUP control statements.
