The DSNAME control option is used to specify a naming convention other than the SCLM default for the project partitioned data sets. The DSNAME option allows the project manager to specify the naming convention for all the data sets in the hierarchy. If the naming convention of the project partitioned data sets will be different for specific groups then the FLMALTC macro must be used so the naming convention for the data sets associated with the specific groups will be changed. For more information about modifying the naming convention for project partitioned data sets see Flexible naming of project partitioned data sets.
