Hi:
That file name looks like an error. The program files (.sas files) in the Programming 1 course folders should all start with "p1". There are 3 folders that should contain .SAS files or program files: activities, demos and practices. All the files should start with 'p1' so if you are finding folders with files that are 'a1', I wonder if you have the wrong zip file.
Then, after the "p1" the next 2 characters are the Lesson or Chapter number. Programming 1 only has 7 lessons, so there should not be an "08" in the next position. The next character of "a" indicates that you should find the program in the activities folder in the class material. Can you either post a screen shot of where in the Programming 1 class you're finding a reference to THIS code of 'a108a01.sas'?
Here's how the reference to program codes can be interpreted and retrieved:
Hope this helps,
Cynthia
