There is a suggestion that SPSS Student Version could be used, but the person suggesting this did not know the limitations of this version. The limitations are 1500 cases and 50 variables. For student use, 1500 cases should be sufficient. If more than 50 variables are required, then the solution is to create multiple files of 50 variables plus one additional "working file" of 50 variables. Paste the required variables from the multilple files into the "working file".
