LoadFile 2
This example loads a data file about cars. Each element is separated
with a tab and corresponds to a different aspect of each car. The file stores
the miles per gallon, cylinders, displacement, etc., for more than 400 different
makes and models. Press a mouse button to advance to the next group of entries.
Record[] records;
String[] lines;
int recordCount;
PFont body;
int num = 9; // Display this many entries on each screen.
int startingEntry = 0; // Display from this entry number
void setup()
{
size(200, 200);
fill(255);
noLoop();
body = loadFont("TheSans-Plain-12.vlw");
textFont(body);
lines = loadStrings("cars2.tsv");
records = new Record[lines.length];
for (int i = 0; i < lines.length; i++) {
