Topic: Can someone post a copy of delnul.lsp

I've accidentally deleted my copy and I can't find it anywhere on the net.

What is it supposed to do?

[JohnK]

is it still in your recycle bin?

[hudster]

Nah it's gone for good, I've checked and I couldn't get it back.

it's a lisp routine that deletes null objects from a drawing, empty text strings etc.

It was handy for cleaning up Architects layouts we receive.
