error handling

[Insener07]

Hody!

I have question about handling error in autolisp(or visual lisp)

I would like that error function to do different things.

The situation is something like this.

i wanna insert an block. In the beginning the lisp routine asks two points and then it inserts an block and a text as well.

If it asks two points it and it sets new sys variables. Right, at this moment if i hit escape it restores old sys variables. If this routine inserts an block it also sets new values for sys variables and if i hit escape at this moment esc the old sys variables will be restored. But i also would like it to delete this inserted block. Now i can't use this (entlast) command. if i hit esc before it has inserted an block it will delete some other object or block which is last object.

Does anybody has a error handling routine which will restore sys variables any time when i hit esc and will only delet an block and text if it is inserted and won't delete last created object?

Complicated huh:((

Thanks,

M

Would you be able to post the routine as it stands so that it could be modified?
