For strings, pass them in as const. That will give a minor performance boost.
For objects, pass them in as var if you need to change the pointer. I don't think I have ever done this myself but there may be a good reason somewhere. Const or by value won't make any real difference as you are just passing a reference. Even if you pass it as const, you can still change the contents of the object. For records, I think you would be best off passing as const.

This is more of a general question than a question concerning a problem. What do you all consider the best way to pass components (TDataSet, TTabControl, etc) as parameters to a function or procedure call? VAR, CONST, or by Value? Which would give better execution speed or memory managent? Is one way of passing the parameters better than another? Thanks James James D.
