what Toad setting is there to turn SET DEFINE OFF for F9

One of the people in our department has her Toad setup such that when she does
an F9 of

BEGIN

Dbms_output.put_line ( ‘abc & def’ );

END;

It does not ask for value for &DEF. If you execute via F5 it does. This is fine.
I would just like to find which setting causes F9 ignore & signs.

Does she have SET DEFINE OFF in her login/glogin scripts?

Right click in the editor, ‘Prompt for Substitution Variables’

I got a syntax error when trying that with your block though, so maybe
there’s another problem/question around the corner.

Outlook quotes cause the syntax error.

The syntax error is probably because outlook put in smart apostrophes.

No. I checked for that.
