HP LoadRunner's Controller

I have to test a set of functions (online functions, batches and web services) for a company and I'm using LoadRunner.
I had no problem creating the scripts with Vugen, but I have a question regarding the parameters file.
Let's say I have 10 scripts, set 10 vusers into the controller (so 1 vuser for each script) and 1000 parameters into the .dat file.
Now I'd want the process to go like this:

- Scripts start and execute at the same time;
- Script1 uses the first 100 parameters, script2 the next 100 and so on;

My question is simple: does the controller manage everything or do I have to set something (like "start from line:") into the script in Vugen to make things go this way?!
