  One thing I do find difficult is stepping through a SP, particularly when it's not doing what you expect it to do.  


No kidding! Actually, this would be a great opportunity for some intrepid software developer (Dave Wellman, maybe?) -- an interactive debugger that simulates a SP. Then you could develop and debug the code before putting it in the database.


  Is there any way of defining functions, for example, which returns a value, or is this effectively just another SP which is invoked from within the main SP ?  


Don't know what you mean here. UDF's can return values, but you seem to be asking something else.


  In simple terms what does ITERATE do with LOOP.  


It returns to the top of the loop, like 'break' in C.


  here's a little technique  


I like it!


  Also, I take it that there's no easy way of returning a result set of values, like an array or, even better, an object ?  


Table UDF's will do this. I haven't looked into them, though.


  Any 'nougats' of wisdom would be appreciated  


I think mine are just nuggets....
