Programming the HP-41C is that easy! The exciting capabilities of
the HP-41C together with the ease of programming and execution make the
HP-41C possibly the most usable, capable handheld calculator system you
can own.

The HP-41C Configuration
|
|
Continuous Memory. The HP-41C maintains all information in the
calculator in Continuous Memory—one of the newest, most advanced memory
systems available in a scientific calculator. All data, programs and
functions—everything in the calculator—are maintained by Continuous
Memory while the calculator is turned off. You can turn the HP-41C off,
then back on and continue working where you left off. In fact, to conserve
battery power, the HP-41C turns itself off after 10 minutes of inactivity.
|
|
Alphabetic/Numeric Capability. The HP-41C is one of the first
handheld scientific calculators to offer both alphabetic and numeric character
capability. Alphabetic characters allow you to name and label programs and
functions, prompt for data with meaningful words or sentences, display
exacting error messages, label variables and constants—even display messages!
