    The file name for the Definitions Pane needs to be "hw3[LastName]Def.scm" where:
  • [LastName] is replaced with your last name.
  • For example, if I were submitting this assignment, I would name the file "hw3WittensteinDef.scm".

    Similarly, the file name for the Interactions Pane needs to be "hw3[LastName]Int.scm".
