in reply to Best practices with globals and subroutine arguments

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.
