To read a specific column from a .csv file into Fortran, you can use the "READ" statement with the "DELIM" option. This allows you to specify the delimiter used in the .csv file, and then you can access the values in the desired column using array indexing.
Yes, you can use the "READ" statement with the "DELIM" option to specify the delimiter and read multiple columns at once. You can also use a DO loop to read in each column individually.
If the .csv file has missing values in the column you are trying to read, you can use the "IOSTAT" option in the "READ" statement to check for any errors. You can then handle the missing values as needed in your code.
To handle different data types in the column you are reading, you can use the "FORMAT" option in the "READ" statement to specify the data format for each value in the column. You can also use the "KIND" option to specify the kind of data type for each value.
There is no specific limit to the number of columns you can read from a .csv file in Fortran. However, it is important to consider the memory and storage limitations of your computer when reading in a large number of columns.
