Hi:
It sounds like you are trying to read one of the National Park SAS tables or Excel files in the Programming 1 course. Can you explain what Lesson you're in and what activity or practice you're working on. The LIBNAME statement you use will make a difference whether you are pointing to a SAS table or pointing to an Excel workbook.
Also, at the top of the table of contents, in the class, above Lesson 1, there is a section called Course Overview and Data Setup. You must follow the directions for YOUR method of using SAS in order to make the data for class. Have you downloaded the zip file in the instructions and run the program as outlined? You will not have any files until you successfully run the data creation programs.
Then, your method of pointing to the National Park (NP) files will depend on what demo or practice or activity you're doing. Many of the tasks in the class have a starter program with hints about what you need to do. So that's why it helps to understand exactly where in the course you're working and whether the data setup was successful and what error messages you might be receiving in the log.
