In order to understand (formally) the concept of 'variable'
we need to have at the least a concept of name(or identifier) -> value mapping.
This mapping is called an 'environment'

Hi,
I have a script (see below) that I want to terminate after X seconds.
The main loop of the program is waiting for user input.
The program enters the main loop and I try to shut down the program
after X seconds from a thread but I can't figure out how to do it. The

The only thing I am pulling is the first element.
I don't understand why the for loop does not go through the entire rss.
