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.
