This was an updated version of the Inform database. It would work on DFS, ADFS and NFS.
The title relied heavily on using overlays to swap in and out procedures as they were needed.
The title included a number of specialist modules such as graph plotting, mapping and report writing.
The example databases supplied with Inform 2 could be used with Inform + although they were not supplied on the disc.
The extensive documentation is needed to run this title and is currently wanted.
