Hi Dan. The main issue about 'our' as opposed to 'use vars' is that the of scope. 'use vars' compiles to a BEGIN block which, wherever it is used, makes the package variables visible throughout the file. An 'our' declaration provides access to a package variable up to the end of the current block or file. You can safely use 'our' in place of 'use vars', but not necessarily vice versa.
