The easiest thing to do until you can properly rewrite the code is to
add a use vars to the top of the file and include all of the variable that
had global scoping.  THen you can go through the code and fix the easy ones
like loop variables (a simple addition of my in the for/while) and such.
Later you can check the rest of them and make them more appropriate.  I like
to my each variable on the first usage (or before the block that it's in if
the scope is beyond the block).
