I’m learning to write simple programs using Fortran. I have a question related to opening, writing and closing a file.
Suppose I want to open a file of name abc.dat in a Fortran code of name fortran.f90. I use the following command:
To write some data corresponding to some variables x and y in it I use
To close the file I use
Here is the problem. Even if I don’t close the file, the program gives perfect output and doesn’t show an error.
Does it mean a file can be left open without closing it at the end?
