Currently only available for OPM RPG.

Interactive Source Debugger for OPM RPG. Similar to the ILE Debugger, but works for Original Program Model RPG Source.
Source is displayed interactively as the program is run and breakpoints can be modified as you see them break. All variables can be displayed/altered at the press of a Function Key.

The next version is planned to work for CLP and ILE CL/RPG.
