I do this all the time, for error handling purposes. I suspect you are getting lost somewhere in the implementation. Epxeriment by simplifying: Create a simple stored proc with one line: x = 1.

Call the stored proc from a command line, and check the value of x. Error. Now declare x public and call the proc, you get the value. You must be doing something else to release the variable.
