Dear Mr. Liebman,

I want to thank you for the opportunity to attend your company's VSAM class in Chicago, October 24th through October 28th. It was an excellent class. Linda Bliden was very professional and a capable instructor.

I hope to schedule another of your classes for early 1984, and I will be recommending your classes to all my clients.
