I want to write data to file after each loop in fortran. Have you some experience ?
To write a file in Fortran, you can use the OPEN statement to open a connection to the file, followed by the WRITE statement to write data to the file, and finally the CLOSE statement to close the connection. You can also specify the file format and other settings in the OPEN statement, such as the access mode and file name.
Some tips for writing efficient and optimized files in Fortran include using the ACCESS = 'DIRECT' option in the OPEN statement for faster access to large files, using the FORM = 'UNFORMATTED' option for faster writing and reading of binary data, and using the RECORDLENGTH option to control the size of the records in a file. It is also important to properly allocate and deallocate arrays to avoid memory leaks.
To read data from a file in Fortran, you can use the OPEN statement to open a connection to the file, followed by the READ statement to read data from the file, and finally the CLOSE statement to close the connection. You can also specify the file format and other settings in the OPEN statement, such as the access mode and file name. Additionally, you can use the INQUIRE statement to get information about the file, such as the number of records or the record length.
Yes, you can write files in Fortran on different operating systems as long as you follow the proper formatting and conventions for each system. For example, you may need to use different file extensions or specify different file access modes depending on the operating system. It is important to check the documentation for your specific Fortran compiler to ensure compatibility with different systems.
You can use the ERR and IERR options in the OPEN statement to specify what action should be taken if an error occurs when writing to the file. You can also use the IOSTAT parameter in the READ and WRITE statements to check for and handle errors when reading or writing data. Additionally, you can use the STATUS parameter in the INQUIRE statement to check the status of the file after it has been written.
