Another option is to use a space character, which reads and skips any number of any whitespace character. I have written something about that here: http://ddili.org/ders/d.en/input.html And this one talks about readln, which may be more suitable in some cases: http://ddili.org/ders/d.en/strings.html And there is formattedRead: http://ddili.org/ders/d.en/strings.html#ix_strings.formattedRead > Forgive me if I'm asking silly questions. There is never a silly question. If a question came up, it is as legitimate as it gets. And welcome to programming! :) Ali

Changing your readf format specifier to include the new line should work.

Thank you!
Adding the \n seems to solve my problem: ```readf("%s\n", )```
I have two further questions about this!
a- What is the difference with this syntax with the exclamation mark?
```readf!"%s\n"(f1.num);```
That is a template.
It'll type check that the format specifier matches your arguments.

b- Do I need to put ```/n``` in every readf statement? I mean,
considering that every input gets entered after pressing intro key (and
I guess this is what introduce the \n)
Yes.
