Programming Basics
The Basics In Brief
Whatls a Program?
A program is a sequence of keystrokes that is remembered by the
calculator. You can execute a given program as often as you like—
with just one or two keystrokes. The stack responds to instructions
in a running program in exactly the same way it responds to an
identical set of instructions executed from the keyboard. The
answer displayed at the end of program execution is likewise the
same as the one you would obtain by executing the instructions
from the keyboard. No prior programming experience is necessary
tolearn HP-11C programming.
Why Write Programs?
Programs save you time on repetitive calculations. Once you have
written the keystroke procedure for solving a particular problem
and recorded it in the calculator, you need no longer devote
attention to the individual keystrokes that make up the procedure.
You can let the calculator solve each problem for you. And because
you can easily check the procedure in your program, you have more
confidence in your final answer since you don’t have to worry each
time about whether or not you have pressed an incorrect key.
The following information covers the operation of your HP-11C’s
programming features. For guidelines that can help you in
planning and developing your programs, refer to page 206,
