of operations, then examples, then a more detailed look at certain features. This makes it easy for you to get a quick picture of how the system operates, if this is all you need.

The functions discussed in sections 1 and 2 of part I and in part II (HP-16C Programming) are similar to those used in certain other HP calculators, while the features unique to the HP-16C are concentrated in sections 3 through 6.

Before starting these sections, you can get a brief introduction to the capabilities of the HP-16C by working through the HP-16C: A Quick Look, starting on page 10.

Finally, the appendices include details on error and flag conditions, lists of operations with special characteristics, and warranty and service information. The Function Summary and Index at the back of the handbook provides short descriptions of every key's function, with page references to more comprehensive material within the handbook. It makes it easy to get the most from your HP-16C!
