IBM® SPSS® Data Collection Interviewer allows you to run a custom setup script when the user first downloads a project. To run a custom setup script, provide a file named runonce.mrs in the same directory as the project (.mdd) file. When the project is synchronized with a remote device for the first time, the synchronization process attempts to run the runonce.mrs file as an mrScript. The script is not run again unless it is changed on the server.
For more information on the synchronization process, see the Interviewer Architecture section in the IBM® SPSS® Data Collection Interviewer Server section of the IBM® SPSS® Data Collection Developer Library.
