what's your opinion

I have an interview next week for SAS/SQL programmer position. Just got an email from the HR, they want me bring some sample code, then explain the code during interview (the sample code that related to the position). The problem is I don't have any SAS sample code, on my resume, I had SAS experience 10 years ago, never keep any code that time. Right now I am a .net programmer, so i can only provide the SQL code. What do you think? I really like this position.
