Q. I have an SPSS system file that I would like to use in another application, such as Microsoft Access. What do I need to do?
A. Most applications cannot read a SPSS system file directly. However, you have several options, depending on the types of files that the application can use.
1. If the application can read tab delimited, fixed ASCII, Excel or dBase files, then you can save the system file out of SPSS in one of those formats, using File->Save As. Select the type of file from the Save As Type drop down list. However, Excel and dBase both have limitations on how many cases and variables can be saved in one file. The following size limitations apply for these file types:
Excel - 255 variables and 16,384 cases. SPSS saves out an Excel version 2 file.
dBase IV - 255 variables and 1 billion cases, subject to disk space. Earlier versions of dBase can hold fewer cases.
2. If the application is ODBC compliant, which would include most modern database programs, then you can use the SPSS Data Driver 32. The SPSS Data Driver allows ODBC compliant applications to read SPSS system files directly, via ODBC. The SPSS Data Driver 32 is included in the SPSS Data Access Pack on the SPSS 10.0 CD-ROM. To install the driver, insert your SPSS CD-ROM. The autoplay screen should appear. Click on Install SPSS Data Access Pack. At the first screen, click Next, and then accept the license agreement. At the next screen, you can select the location where you want the files to be installed. Then click Next. At the Select Components screen, check the box next to SPSS Data Driver 32. Then, click Next and follow the remaining steps in the wizard. This will install the SPSS Data Driver into your ODBC Data Sources Control panel.
To configure the driver, go to Start->Settings->Control Panel. Double click on Data Sources (ODBC). On the User DSN tab, click Add. Scroll down until you see SPSS Data Access 32 (*.sav), and select it. Click Finish. A small dialog box will appear, named Setup. In the box next to Data Source: type in a name for the Data Source. In the box next to Database: type in the full path to the directory where you SPSS data file is located. Then click OK. Click OK again on the Database Administrator. When you use the data source within your application, the driver will display each SPSS data file in the directory as a separate table. In general, ODBC can only read in 255 variables at a time.
