Forgot I still had this available, albeit a Windows XP build.
Visual RPG (aka "CodeStudio") is a PC Windows XP-based editor for RPG IV, DDS, and other languages. It was original sold to AS/400 developers as a "CODE/400 for Windows" product when there was no Windows-based "CODE/400" (they only did an OS/2 version).
Later it was renamed to "CodeStudio" and that trademark was purchased by a multi-national corporation and the product name was changed back to its original "VisualRPG" and provided at no-charge with no support.
It uses FTP to pull down the source from the host and save it back up to the host, hence the source statement change dates are lost.
