FmPro Script Diff, a utility that compares, edits, searches and stores scripts made using FileMaker’s ScriptMaker. FmPro Script Diff costs $100.
The software displays difference line-by-line using color coded tags. XML source code can be updated or edited using the Search & Replace feature, then pasted back into FileMaker Advanced. You can also copy the scripts as RTF-formatted text for documentation. Each script definition attribute is copied onto the clipboard.
System requirements call for Mac OS X v10.2 or later.
