However The variables ARE defined.
No, they're not. Your subroutine is frobbing %Data99::WasonE, which is a different variable than the lexical hash %WasonE in the main program. Welcome to namespaces.

Read perldoc -f package, perldoc -f my, "Packages" in perlmod, and "Private Variables via my()" in perlsub. To see what's happening, try using Data::Dumper to dump the values of your variables at various points.
