FORTRAN IV Example Session
Using FORTRAN requires you to imagine you're using an imaginary key punch machine producing a card deck. Formatting is important. To make things easier, set !TABS 7 to get to the CONTROL column from there you can <SPACE> once to get to the STATEMENT columns.
- Putting a C in column 1 denotes a comment which the compiler will ignore
- Statement numbers can be in columns 1 - 5
- Column 6 is reserved for C aka TRANSFER CONTROL TO STATEMENT
- Columns 7 - 55 are typically used for STATEMENTS
