This question doesn't make much sense to me. If you know how to output one value there should not be a problem to to the same thing again.
Show us an example of how your outputfile should look like.

So you want an instant code that reads an ini file? is that it?

@ Zuk:
have you ever opened a .ini file,kinda like that

@ ioko:

So you want to write to an ini-file but it could be a different format as well.

Now I understand you know how to write one value to a file but you don't know how to do it multiple times.

Now I know that you actually don't want to write a file.
It's reading an .ini file what you really want.

And yes I have done that before. It's very straightforward.

Code:

read a line from the file
    if the first non whirspace character is a '[' its a section. cut the '[' and the ']' and you have the name of the section.
    else if  the line contains a '=' the part before the '=' is a variable name the part after the '=' is the value.
       now you just have to check if the value-part is a number or a string
continue until eof is reached.

show some code that we can help with actual problems and don't let us guess about your intentions.
