Pascal For Loop

• Syntax:

      for var := initial (to | downto) final do 
          statement
  
  

• Design Choices:
  • Loop var must be an ordinal type of usual scope
  • After normal termination, loop var is undefined
  • The loop var cannot be changed in the loop
  • The loop parameters can be changed, but they are evaluated just once, so it does not affect loop control
