One of the unique features of Fortran is its use of fixed-formatted source code, which means that code is written in a specific format with strict rules for column placement. This can take some getting used to, but it helps to make the code more readable and easier to maintain.
In the next section, we will take a closer look at the syntax of Fortran programming, including some of the basic rules and conventions that you need to know in order to write effective Fortran code.
