In SPSS for Unix, how do I increase the workspace (memory)?

Use the -s parameter to increase the workspace allocation for your SPSS job in Unix. (The workspace is the number of bytes of system memory allocated to working storage space for your job.)

To increase the workspace allocated to a noninteractive job, use the following command:

Replace workspace with an appropriate amount of storage space (e.g., 800k, 100k, 2M).

Note: Be sure to use lowercase k for kilobyte, and uppercase M for megabyte.

Replace inputfile with the name of your file containing SPSS commands. Replace outputfile with the name of the file you wish to create for your job's output. For example, suppose you have an input file called regres.sps. To execute the job with 800KB of workspace memory, submit the job with this command:

The output file created in this example will be called regres.out. The option -s 800k increases the workspace.

You can also use the -s parameter to increase the workspace available for interactive SPSS sessions, for example:

In this example, 600KB of memory is allocated for your interactive SPSS session.
