Since you've already put the obsolete code in the old fashioned way, Sally, just replace the old code with the new code by doing a global search and replace. You can generally do this with a good text editor.
Get some guidance in an appropriate forum here when you're ready to do it. It's not rocket science, but it pays to be careful.
