IBM SPSS Statistics Level 1 v2 — Question 24

When you read or write to a sequential file, and wish to have a value be identified with DataStage as NULL, which of the following is the correct option?

Answer options

• A. Set format’s fill char option using the value
• B. Set string type default option using the value
• C. Set format’s null field value option using the value
• D. Set $APT_IMPEXP_REJECT_NULLS using the value

Correct answer: B

Explanation

The correct answer is B because setting the string type default option allows you to specify how NULL values are represented. The other options either modify different settings that do not directly affect NULL identification in this context or are not relevant to the requirement of identifying a NULL value in DataStage.
