Last week, I heard a statistician refer to an area called "multilevel
programming" (MP). The person was saying that there are several
software programs for MP. I am not sure what MP is. I googled it and I
am still confused. I would appreciate it if somebody could give me a
pointer. Many thanks!

I've not heard the term "multilevel programming". Perhaps the
statistician meant "multilevel models" (aka, hierarchical linear
models, and several other names). Here are some notes on that topic.

An introductory level book I found helpful was the one by Jos Twisk.

The book by Snijders & Bosker is more complete, but also a lot more
advanced.

I think one of the standard programs for fitting this type of model is
named HLM. (Not to be construed as an endorsement: I've never used it,
just heard of it.)

For a quick start with R you may have a look at the R newsletter 3/3,
available at the R-project homepage.
The newsletter has an article by Lockwood et. al and they show how to
fit multi level models with R. Their example is the classical student
performance study.
