Input-Output parameter

Question

I have something like this,

 def input-output parameter table for tt1.

Please can you explain what input-output param is and how to use it in simple terms , The Definition is not really making sense at this moment in time.

Thank you

Answer 1

An input output parameter is a parameter that is passed to a procedure that can then be updated and passed back. In this case you will receive a temp-table as a parameter that you could update and is then passed back.
