THE MARKER CARD
As you learn to use the en-gram POCKET CARDS™ system you may find yourself constantly flipping through and scanning a stack (deck) containing about 15 or 20 cards, one of which should always be a green “marker” card.

Several of these green “marker” cards came packaged with your original en-gram POCKET CARDS™ kit. I recommend that you carry one with you at all times. Its purpose is twofold: 1) to provide a location for your Personal Coding Library, and 2) to mark the “last-card-scanned” position in your card stack. This is so that whenever you’re ready to continue scanning our cards, you will be able to quickly locate the place where you last scanned.
Card Colors
En-gram POCKET CARDS™ come in four different colors: white, blue, green and gray. Use the different colors at your discretion. An example would be to designate a blue color for all of your ideas or book recommendations.
