Description of the
Sample Program
Getting Started 2-2
Before reading the examples in this chapter you should already know
how the emulator operates. You should know what the various emula-
tor prompts mean, and you should know how to use the emulation
commands. Refer to the appropriate Terminal Interface: Emulator
User's Guide manual to learn about the emulator; then, return to this
manual.
The sample program is used to illustrate analyzer examples. The sam-
ple program is written in assembly language so the disassembled trace
listings will be more meaningful.
The examples in this chapter have been generated using an 80186 (HP
64764) emulator. The sample program is written in 80186 assembly
language.
It is not important that you know the 80186 assembly language; how-
ever, you should understand what the various sections of the program
do and associate these tasks with the labels used in the program.
You are encouraged to rewrite the sample program in the assembly
language appropriate for your emulator. Then, you can use your ana-
lyzer to perform the examples shown in this chapter. Of course, the
output of your commands will be different than those shown here.
A pseudo-code algorithm of the sample program is shown in figure 2-1.
The sample program is not intended to represent a real routine. The
program uses four different callers of the WRITE_NUMBER subrou-
tine to simulate situations in real programs where routines are called
