Hi,
That program looks trivial, and most of it would go when re-written in CCS 'C'.
It would help if we knew what the program was supposed to do? It looks like you simply want to sound a buzzer whenever a PIR (passive infrared sensor) detects motion? Is that correct?

Sorry, but this is almost too easy.
I don't mind to help you, but if you don't learn the basic knowledge then you will never be able to program by yourself.
The program you posted is a bit difficult to start with because there is a lot of initialization code for the hardware that is different for each compiler. The easiest way to solve that is by throwing that part away and start from scratch. Start the CCS compiler and use the Project Wizard to start a new project. This will guide you through all possible options for setting up the hardware and gives you a good project start.
The next part will be to convert the main part of the original program to your new project. Surprise! This is only 4 lines of code! I'm sure you can do that yourself. 
When you do get stuck, then post the code as far you have it and we will help you further. |

This is not a 'write code for you' forum.
In CCS, this could be done in about 10 lines, but nobody is going to do this for you. Try yourself, and post what doesn't work, then we may _help_. Ckielstra's answer is the only one you are going to get, especially if you SHOUT. |
