**__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**
