The DSS Output tab of the Alternative Editor allows the user to optimize write time to the simulation.dss output file by specifying which elements and variables should be written to the file during a compute. The DSS Output tab contains a tab for each DSS output element, i.e. Reservoirs, Reaches, Diversions, Junctions, and State Variables ("Figure: Alternative Editor - DSS Output Tab Default").

Initially, the Output All DSS Records check box is selected and all element tabs are disabled. All DSS output will be written to the simulation.dss file. If the Output All DSS Records check box is unselected, the element tabs will become available and the user can check DSS data to not write.

To select DSS data to write to the simulation.dss file at the end of a ResSim Alternative compute, the user would check the row (specific element) and column (variable) for a particular output variable. The top row of checkboxes represents all elements and variables in the table. The user can select or unselect the entire column using the all checkboxes. Individual elements and their single variables can be selected/unselected by checking/uncheck the checkbox in the (specific element) and column (variable) for a particular element. The top checkbox displays a third state, which indicates various rows are selected for that column.
