  • Passing arrays to functions/subroutines
  • Friendly advice
• Bad practices
  • Common blocks
  • implicit.h
  • SIXLTR variables
  • Fixed-form
  • Large static arrays
  • Long subroutines
  • Functional programming features
  • Elemental functions
  • Pure functions
• Good practices
  • Version control
