Programming the HP 30b
This chapter applies only to the HP 30b, and explains how to program specifically on the HP
30b. If you are unfamiliar with the basics of programming, you may have trouble
understanding some of the following information. Reviewing the material and practicing the
concepts illustrated below will help you understand how this feature works on the HP30b.
The HP 30b Business Professional is a powerful business calculator, but it may lack a function
important to you. The HP 30b programming functions allow you to create up to ten programs
to fulfill your needs. In order to keep the calculator keyboard clear and consistent, the
programming functions are not written on the keyboard.
However, included in the calculator package, you should find an overlay which shows the
programming functions. This is designed to be placed on the top surface of the calculator and
left in place for the life of the calculator. If you are interested in programming the calculator,
you will need to place the overlay on your keyboard before getting started.
Key Presses for Program Instructions
Enter the Program menu by pressing : followed by E. The instructions specific to
programming (illustrated on the overlay) are inserted by pressing : and simultaneously
pressing the key with the desired programming instruction. Then release both keys before
pressing any additional keys for your program. In the following chapter, this combination is
represented in the following manner:
(HOLD)
This sequence is identical to using the shift key on a computer keyboard to invoke the shifted-
function.
For reference, the table on the following page lists the keys along with their associated
programming instructions.
