I've done this and the information is like a scattered puzzle piece on the forum.
Here are the steps, just add the macros:
1- Initiate Counter
2- Set path to file
3- Get number of strings from file
4- Get counter's value
5- if counter's value < number of strings
5.b- NO then pause / stop
6- yes get line from file at counter position
7- increase counter => Go 4
That's about it
