# Interface: Straight-Sum Windows

The Straight-Sum windows are used for adding fields to the modeler, for future expansion. A straight-sum field is one where each rack has a value which is totaled up for each combination, and that total compared to a station-wide limit value (stored in the runs table). "Stowage" cold be a straight-sum field; "MTL" could not (since it's totaled for each module, and the value is affected by RFCA instead of being a straight sum). This window is what opens when you click "Straight-Sum Fields" in the window menu. It is a list of all the currently defined fields; double-click one to edit it. |
A window like this one will appear. The window has a set of text blanks for the fields associated with this field (you may want to resize the window to make it easier to use). The fields are limited to their associated type, i.e. a row that's a number can only be set to a number. After modifying the row data, hit the "save" button to make the changes final. Descriptions of what each field are can be found here. Note that you don't have to edit the color fields manually; you can click the "set color" button to bring up a color selector dialog. |
To make a new field if it's required for your straight-sum resource, click "Add New Field" in the Window menu. A window like this will appear, allowing you to enter the new field's name, table, type and default value. Remember that field names must be unique in tables. Most of the time, the fields for straight-sum resources will be of type "double", for double-precision floating-point value. |
