Loading an LDW Analysis You can load an LDW analysis by using the File::Open option. When you select this option, you will see the standard Windows file open dialog box. If you have made changes in your previous analysis without saving them, LDW will let you save them before you open the new file. LDW saves the analysis using the last file name used, as in the File::Save option. Importing Data Into LDW The File::Import option lets you load data on a set of alternatives from another file format. You can use the Import option to import alternatives data from dBASE III Plus (.DBF) files, Microsoft Excel worksheet (.XLS) files and from comma and tab delimited files. You can use the data to create a new LDW analysis or to update and/or append to the data currently loaded into LDW. When you select the Import option, you will see the dialog box in Figure 8-55. 8-64 Section 8 -- Using LDW 3: Reviewing Results

Figure 8-55. Dialog box for File::Import Option. The radio buttons at the bottom of this dialog box allow you to select from the following options: ! Create -- create a new LDW analysis. ! Import Structure -- scan a file and create a new LDW analysis. Import the measures identified in the file, but don't import any alternatives. ! Append -- add new alternatives to the data currently loaded into LDW ! Update -- modify the measure levels of the current alternatives. The update option assumes that you have already created or loaded an existing data file into the program. LDW will match the data in the input file with the alternatives and measures in the existing analysis. The previous levels of some or all of the measures will be updated based on the data in the input file. Section 8 -- Using LDW 3: Reviewing Results 8-65
