in reply to Insert a meter only once

Your program will be mostly in perl rather than french, so it should be ok ;)

This is just guessing; perhaps you mean 'tallies' or 'statistics' or 'summary'.

I imagine you have a loop to iterate over the words and print them. It sounds like you have the print statement for the "meter" inside the loop, so it prints each time. Simply moving it outside the loop will make it only run once.
