If you create a frequency table of this variable (Analyze > Descriptive Statistics > Frequencies), you will notice something strange: The dataset has 435 observations in all, and SPSS reports that there are zero missing values. I'm trying to use Python in SPSS to recode observations by row. Notice that the "missing" category ("999") was recoded last, even though it is alphabetically before the category names. In this situation, you must use Automatic Recode in order for SPSS to recognize blank strings as missing values. Recoding several variables into several new variables is straightforward: simply fill in multiple input variable names after RECODE and multiple output variable names after INTO. The command Into Same Variable replaces existing data with new values, but the command Into Different Variables adds a new variable to the data set..
