Introduction
Figure I-2. The Same “Random” Program in VEE
In VEE, the program is built with program elements called
objects. Objects are the building blocks of a VEE program. They
perform various functions such as I/O operations, analysis, and
display. When you view the objects with all of their connections,
as shown in Figure I-2, this is called the detail view. The
detail view is analogous to source code in a textual
language.
In VEE, data moves from one object to the next object in a
consistent way: data input on the left, data output on the right,
and operational sequence pins on the top and bottom.
The objects are connected together to form a program. Follow
the program from left to right. In the “Random” program shown
in Figure I-2, a random number is added to the Collector -
Create Array object ten times, creating an array. Then the
program finds the maximum value in the array, and displays the
Max Value and the Array Values.
