@April2211 You are posting questions to a thread that has been marked "solved," but it is not clear whether you are asking the same question of a new question. To maximize the chance that your question will be answered, start a new thread. Post your question, the code you have tried, and sample data, if possible.  You can link to an older thread (like this one) or to a blog post or SAS documentation if those resources are relevant to your question.

In general, these tips are helpful for getting a fast answer to your question. The article includes lots of great advice, including, "Don’t post a new question on an old discussion thread."

Thank you for your advice! I just think the contributor in the present post will understand this question better. I am a new SAS user. And I am very sorry with posting a new question on an old discussion thread.
