Please, write out the question you have, simply using the title is not enough. But looking at the code you posted without any furhter explanation about the type of error, I think this is the culprit: > [@soumaya](#): > > READ(153,_)_ There is no proper format or the like. ---

thank you When I compile the code, this message appears. The program starts reading the file but it cannot read it entirely. ---

What compiler and what platform? It seems strange to me that the program gets built at all. Are you sure there is a new executable based on this code? ---

That is a blast from the past! Could you try it with, say, gfortran or Intel Fortran oneAPI? Lahey Fortran is very old indeed. ---

> [@soumaya](#): > > WRITE(_,_) ‘DEBUT DE LA LECTURE DE FICHIER DENSITE’ Are you using a _modern_ AZERTY French keyboard, or even bépo and typed the snippet of code ? To get the first line working, I noticed completing the instruction for `write` is not sufficient. ```f90 program test ! WRITE(,) ‘DEBUT DE LA LECTURE DE FICHIER DENSITE’ WRITE(*,*) 'DEBUT DE LA LECTURE DE FICHIER DENSITE' end program test ``` It is difficult to see, so I enclose a screen photo: ![danger](https://global.discourse-cdn.com/free1/uploads/fortran_lang/original/2X/c/c0661a576f5e20c73388020bf25a6eb13a3b1a92.png) When enclosing a string, refrain from _these_ single quotation marks which appear similar to a small `6` or `9`, with a small droplet you find below `7` and `8` on the top row of [AZERTY amélioré](https://www.mpi-inf.mpg.de/news/spotlights/2019/azerty-ameliore-french-keyboard-layout-optimized) (published 2019)\*. Either use straight (English) double quote sign/double prime `"` as used as unit of foot/feet (below `3` in the top row, elder AZERTY), or the straight `'` below `4`. If you continue to use AZERTY amélioré, at least both characters safe to (pairwise) enclose a string in source coded join one key in common (top row, right to `0`). Not all type families render the difference between the difference between accents, primes/double primes or feet/inch safe for source code vs English single/double quotes clearly, above I used [FiraCode Mono Regular](https://github.com/tonsky/FiraCode). In a good editor (above I used [geany](https://www.geany.org/)), there is [syntax highlighting](https://en.wikipedia.org/wiki/Syntax_highlighting) to help you here. \* Almost a _poisson d’avril_ they published this on an April 2nd. ---

@soumaya , post program code using the “format as code button”, icon \ in the toolbar. Without that, the code gets mangled and ambiguous, and replies based on guessing what the code was can be confusing.
