I know that I should already know this, but it's been a while....I've  
slept since last attempting this years ago....

How does one insert data into the middle of an existing list?

For instance, I have a list of items, including lists. I want to  
insert an item into a new second position in the original list.

Here's the original list....

Set myList to {itemA, {itemM, x}, {itemP, y}}

I have a new itemZ that I want to put in as the second item of myList  
that displaces the current second and third items to be items 3 and 4  
of myList, with itemZ as the new second item.

The new list should look like....

{itemA, itemZ, {itemM, x}, {itemP, y}}

Is there a simple call to do this? Or do I need to set up a complex  
handler?

Chuck
