A couple quick questions...

1. You can probably use multishell.getTitle for 1 through multishell.getCount() to get a list of programs. I'm not certain if the title is set to the program name, though. This also assumes you aren't using your own coroutine manager and are running everything through multishell.

2. What do you mean by update? Coroutines are one of the most (if not the most) advanced topics in ComputerCraft. You shouldn't be using them if you don't understand what they are, and how they work. I recommend reading this tutorial.

3. No, you don't. You can look into the http API to get data from websites. I would recommend putting your code in a github repository.

I have some comments for the OP in responce to this post

1. It defaults to the program name but the multishell API provides a function to set it as well. http://computercraft.info/wiki/Multishell_(API)
2. have a look at this - http://www.computercraft.info/forums2/index.php?/topic/10540-
3. I have a tutorial for that, some of it may not be relevant to your needs. The section you want is "Making a Big Project" but you may want to check prior sections too http://www.computercraft.info/forums2/index.php?/topic/26002-

Thanks for responding! For courotines,I didn't mean update. I meant I need to add and remove them without breaking other. I tried parallel API but it does exactly what I don't want it do.

You could take a gander at the parallel API to see how it works, it is a built in coroutine manager

Needless to say, multitasking operating systems are very difficult to create well and as a result many OSes posted often lack many features and aren't worthy of the name OS. Not to say you can't do it, I don't know how much experience you have, this question and your post count leads me to believe you are a beginner and you may want to invest time in learning Lua in its entirety. Good luck regardless.
