Declaring Variables

Variables can be of any type (later).

• Use ``IMPLICIT NONE''
• This will force you to declare all vars before use!
• Declarations come first in the program!

  Program Vardemo
   Implicit none  ! **must in all cs101 programs**
   ! declare all vars first
   Integer :: Max, Min
   Real ::  Radius
   ...
   ! then write the code..
