Under the menu bar is the device bar, an array of commonly used features derived from the menu bar conveniently placed in clear view for straightforward access and usage.
Do the rows and columns in the program window remind you of one other program interface? SPSS uses rows and column in a lot the same way Excel does. In SPSS, by default each column is labeled "var" which is short for variable. The variables are the survey items or the questions you'll ask respondents.
