Following the ongoing discussion [on the use of other (human) languages](https://fortran-lang.discourse.group/t/should-fortran-discourse-be-open-to-languages-other-than-english/385/22), as a demonstration, this is the raw automatic translations of @said 's question and @gardhor 's answer, from French to English, obtained with [https://www.deepl.com/home](https://www.deepl.com/home)

_Hello,_  
_I have a program with a loop, and I would like to save several files (data.txt ): at each run create a file whose name depends on the index_

_thank you for your help._

_program ex4_  
_open(10,file=‘data.txt’)_  
_…_

_Hello Said and welcome._

_To complete the previous answer. The index of a loop in fortran must be an integer (the possibility to use a real has been removed)._  
_Probably, you should read up on the fortran language. For example in French :_

_[http://www.idris.fr/media/formations/fortran/idris\_fortran\_base\_cours.pdf](http://www.idris.fr/media/formations/fortran/idris_fortran_base_cours.pdf) 2_

_There is also a discussion on this forum about books and documentations:_

Note the “2” character at the end of the first link, which is the number of times the initial link was clicked. I kept it on purpose, but we should of course remove it to avoid confusion.  
In Said’s question, I have just added a “:” after _(data.txt )_ in the French text to improve clarity.
