I rarely, if ever use global variables, they don't really provide many benefits over objects or local variables and can potentially lead to many bugs.

If I were you, I would stick all my data into a readonly data object. Then you can pass your subroutines the data object instead. This way you can make your data specifically 'READONLY', ie: no gotchas which your subroutines "accidently" change a value.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
