When this program reads in a positive number, how come it prints both messages "positive" and "negative" but I need it to print only the message "positive"
Any help is appreciated. Thanks !

Have a look at the code that follows the label message2 - You dont have a jmp instruction in there. As a result, after printing "positive" the code 'falls-through' to the next case and then prints "negative".
I guess you intended to jump either to forever or to finish.
