SPLIT FILE OFF. **Optional additions: Scripts referred to below can save work and speed process of communicating output **. **First, since this example may be useful for adding groups or batches of data to a larger file, a time identifier may be helpful **. **You could begin program with a script that asks the user to specify time related data such as month and/or year **. **This time specific data then becomes part of the dataset and can be passed to the Report Title via ')var' where var is the name of the variable passed **. **See Raynald Levesque script at: http://pages.infinit.net/rlevesqu/Scripts/dialogs/GetFyFromUserThenRunSyntax.txt **. **Near the start of your program you would insert a statement similar to the following where you specify the path to the script **. **SCRIPT FILE='C:\\--(substitute your path here and use sbs name extension)--\\GetFyFromUserThenRunSyntax.sbs'. **. **Second: You could run the SPSS Clean Viewer script that deletes unwanted output **. **See http://pages.infinit.net/rlevesqu/Scripts/OutputDoc/DeleteStatisticsAndCaseProcessingSummary.txt **. **SCRIPT FILE='C:\\--(substitute your path here)--\\Clean Viewer.sbs'. **. **Third: You could run a script that exports your output to MS Word for printing **. **See Raynald Levesque script at: http://pages.infinit.net/rlevesqu/Scripts/ImportExport/ExportVisibleOutputToWordViaHTML.txt **. *Fourth: If all output were going to the same person, you could run a script that emails output to programmed address. **See Raynald Levesque script at: http://pages.infinit.net/rlevesqu/Scripts/ImportExport/SendDocumentByEmail.txt **. *Next command restores settings preserved at start.
