Normally, it shoudn't be a problem when you add new variables without modifying the structure of the other variables.
Once the questionnaire has been modified, use the option 'Tools / revise data file'.  In case something goes wrong, a backup of the data (prior to modifications) is stored with '.OLD.REC' extension.
