Google "Hungarian Notation" \:\)

Basically, the first 1 or 3 chars are used to identify the type of data that a variable will usually contain.

I tend to take liberties with my ancestry ;\) - I only use an "a" to differentiate between arrays and simple vars in most cases, although I do use an "o" to reference COM Objects.
