Netlogo, changing exported file name

Question

**I am trying to write information to a file for some experiments. Is it possible to change the file name for each experiment without having to change the code each time?

I was trying to use a slider to change the file name but had no luck. **

Answer 1

you can try

file-open (word "mytrack" fileName ".txt")

word strings together its arguments and converts numbers to strings in the process.
