Procedure execution in YUKON

Hi all,
I wanted to ask...if there is someone who worked with pl/sql developer as well...then i wanted to know how can i TEST in the sql server like we do in the PL/SQL developer using the STEP IN we can test our procedure step by step...so how can i do the same thing in sql server?????
or generally also,if someone knows how can i execute a procedure without using the execute command explicitly...so,that i can put values first by using like EXECUTE STORED PROCEDURE or anything n then watching it how is it going step by step????????
thanks in advance...

In SQL 2000 we already have a debugger built into the Query Analyzer, so I assume there will be something similar in SQL 2005 too. Yukon is still in beta, so it's probably not feature-complete.
