Input Data Editor
The Input Data Editor is accessed either by choosing the Edit option from the Functions menu or by clicking on the Input Data Editor button on the toolbar. The Input Data Editor window contains a tree diagram of the blocks and tables of HSPF. The tree diagram is navigated by clicking on an item name. Double-clicking on an item name reveals the subitems within that item, if any exist.
Double-clicking on a block or table name produces another window containing a grid for editing the parameters of that block or table.
