Когда SAS встречает неинициализированную переменную, она выведет примечание в журнал, который выглядит следующим образом:
NOTE: Variable not_in_data is uninitialized.
Возможно ли, чтобы сообщение SAS выводило это сообщение как предупреждение или ошибку?
Да (в версии 9.4 или новее):
option varinitchk = error;
Значение по умолчанию note, возможны другие значения nonote и warning.
Существует также недокументированная функция, которая изменяет некоторые примечания к ошибкам. Вы можете либо установить опцию, используя option dsoptions = note2err; или добавлением / note2err в инструкцию данных. Я нашел список на SAS-L заметок, этот вариант изменяет на ошибки:
