PBDelta understands PowerBuilder source code, when PowerBuilder saves or regenerates objects it quite often moves blocks of code around inside the source file. PBDelta allows you to diff multiple selections of files or folders, you can select a PowerBuilder library and compare it against an exported set of source files, or you can compare a recursive project folder against another project folder from an older version. PBDelta improves the standard diff type tools in three ways: PBDelta is specifically design to compare PowerBuilder objects and produces a tailored results view which is easier and more accurate that a standard 'diff' tool. PBDelta is a utility designed to highlight the differences between versions of PowerBuilder application source files.
