Not compiling? I'm not surprised: Where did you find this structure?
If you want an anonymous block then get the procedure declaration out of there.
If you want a stored procedure drop the word DECLARE and put your variables into the correct place before the BEGIN.
Look a the demos here:

Likely your types should either be stand-alone types or declared in a package header.
