Thanks for the Help so far, but now I detected my real problem, because if I debug your script it works fine! My problem now is that the Regexp Vars I am looking for are lexicaly in a sub (or any other kind of block), as if they where declared with my (or local). If I qualify them with the package name and look in the symbol table, there they are, the only think left to do, is to look in the lexical scope of a block.
Btw. I am using the "original" perl debugging mechanism, means my script is included in the executing script at line 0 in a BEGIN Block. Then I only need to use the internal debugging functions from Perl (DB and sub). I thought this was the "Perl" way of doing this.
