More Design Issues

• Case sensitivity
  • Disadvantage: readability (names that look alike are different)
  • worse in Modula-2 because predefined names are mixed case (e.g. WriteCard)
  • C, C++, Java, and Modula-2 names are case sensitive
  • Names in most other languages are not

• Special words
  • A keyword is a word that is special only in certain contexts
    • Disadvantage: poor readability
  • A reserved word is a special word that cannot be used as a user-defined name
