This would leave the space available within your quota free of the large raw data set while SPSS is creating and saving the permanent SPSS save file.
By default, SPSS allocates 512K of main memory for your session and its tasks. You can increase this working memory by invoking SPSS with the -s switch followed by a number with K (kilobytes) or a number with M (megabytes). For example, if you wanted to invoke SPSS in a 5 megabyte workspace, you would type
spss -s 5m
at the UNIX prompt.
