[Lazarus] Teaching Pascal at College

Because there are some basic controls that use array logic (lists, combo 
boxes, even edit boxes when dealing with positions of characters in a 
string), I'd introduce the concept with the variables. If the student 
can make the connection between the visual controls and concept of array 
logic, the inserting, selecting, and manipulation of that data should be 
easy to grasp.

Considering your audience, it should fit in with stuff they are already 
familiar with, just not thought of in the way of how a computer 
organizes memory?  Meh, may be I'm getting too far down into the weeds.
