the edit provided for scripts has only cut, paste, copy What can I do if I need for instance to search for places where I used a certain variable or function in a long script or even better I want to search all scripts to see in which script I used a certain variable.
Can I link to a certain word processor? or is there a facility in FM I am not aware of.
Not in regular FileMaker Pro. In FileMaker Advanced, you can generate a database design report and perform text searches on this report.
From regular FileMaker, the only thing I can think of is to print the script to a PDF. On windows systems, you'd need to acquire a PDF printer to do this. Once you have a PDF of your script, you can do text searches of it in the PDF.
