How to make a loop
Now let's try to make a loop over an array to create a new variable 'list_firstnames' containing firstnames.
We'll write in the script windows :
1 2 3 4 5 6 7
Note1 : first I create an empty variable 'list_firstname', then i make the loop to extract the data I want.
Note2 : x is the current element of my array. Will be
my_array the first time, then
my_array the second time etc....
