Consultancy and Bespoke solutions

Since 1979 Grange have been supplying consultancy and designing systems for Customers particularly in the areas of interactive communications. Initially these systems were based on the IBM mid range computer systems, using BSC and SNA protocols. More recently systems have been designed for TCP/IP environments.

Our specialisation is to create purpose built systems that allow interactive communications between systems, using TCP/IP sockets protocols.

Our skills include sockets programming for IBM iSeries and Windows.

Programming for the IBM iSeries is in native RPG1V, and for Windows we use the high speed development environment of Delphi.
