4. Backward and Forward compatibility
Very important in the introduction of a new programming language standard is that old programs (at least those who obey the outgoing standard) can be used once again, with the new standard. When we went from Fortran 66 to Fortran 77 the extended DO -loop was removed (the extended DO -loop means that if you do not change any of the DO -loop parameters you can jump out of the loop and then jump in again (this is somewhat contrary to the concept of structured programming). ... 2, June 1993, page 1. ...
