Variable for inserting blocks without dialog box

Hello there, I can't remember which variable it is I need in order for the following to work:

I have a lisp for annotating co-ordinates. I insert a little block, then run the lisp which allows me to click on a point and have a little co-ordinate box appear.

When I do this though, a dialogue box pops up to prompt me to enter values, rather than just filling the values in automatically. It's been years since I've had to change this setting, so I've forgotten. It's the setting that allows you to insert a block with attributes without it prompting you with a dialogue box.

Thanks for your help!

the variable in question is called ATTDIA.

In this instance it would require a setting of 0 (zero).

Thank you, that's excellent! This forum is priceless!
