Automated SQL Stored procedure functions

I was tired of writing code to execute store procedures so I wrote these functions that do most everything for me. Just supply the stored procedure name and an array of parameter values. Also provide a recordset or return value variable depending on what function you are using. SAVES ALOT OF TIME! There are some examples subs at the bottom...
