I'm using korn shell to connect to oracle, retrieve certain values, put them in a list, and iterate through them. While this method works, I can't help but think there is an easier method.
If you know of one, please suggest a shorter, more efficient method.

NAME
gvrng - An interactive, introductory programming language.
SYNTAX
gvrng [world file | program file]
DESCRIPTION
Guido van Robot is a project developed by advanced high school students for use by their peers as a learning tool and precursor to the fur-
ther study of programming with Python. It is a minimalistic programming language providing just enough syntax to help students learn the
concepts of sequencing, conditional branching, looping and procedural abstraction. It's biggest strength is that it permits this learning
in an environment that combines the thrill of problem-solving with instant visual feedback. In short, it is an interactive, introductory
programming language that is excellent for learning the basic concepts of programming, applicable in any high-level language. Best of all,
it's a whole lot of fun, too!
At this point, you are probably asking yourself, "What is GvRng, specifically?" The gist of it is that it is a robot represented by a tri-
angle on the screen that moves around in a world made up of streets and avenues, walls and "beepers", which Guido can collect or set. His
actions are completely guided by a program written by the user.
