Question: programming proc using packages scope


   A question on programming Procedures (proc).

   What is the best, or most common method, to invoke packages within proc or at the worksheet level?

   I have always been confused about Proc scope for packages.   I use Scientific Constants a lot.   It and several other "with(package)" are part my main loaded pakages right after restart command.   LinearAlgebra is another common used package.

   It has been a question for me of whether to implement a "with()" statement inside of the proc to bound the scope or ensure it is seen/available by the procedure for the available commands inside the packages.  

  All thoughts appreciated.
