How Do I Run SPSS Jobs with More Memory?

In SPSS, working memory is allocated as needed during the execution of most commands. However, the procedures like Crosstabs, Means and Nonparametric Tests, take all of the available workspace at the beginning of execution. If you get a message suggesting that more workspace memory is required, you can increase the Special Memory Workspace Limit in the General Options window. After you are finished with the procedure, you should probably reduce the limit to its previous amount (the default with SPSS 10.1 is 512K), since an increased workspace allocation may reduce performance under certain circumstances.

To set General Options:

1. From the menus choose:   Edit -> Options.
2. Click the General tab.
3. Select the settings you want.
4. Click OK or Apply.
