Been doing Mumps/Caché technology for around 40 years.  Started with DSM11 on PDP, then moved to Datatree (a fine product) and them Migrated to Caché when they took over DataTree.

Over the years I have used 

• Plain Mumps
• MDM from Hoskyns
• SAT Developer
• My own telnet framework
• CSP
• ZEN for the last 11 years

Along the way I picked up Delphi and Visual Basic and Microsoft Access.

My philosophy has always been to use as few tools environments as possible and concentrate my intellectual efforts on designing, implementing and delivering bespoke business applications.

One of the great things about Mumps was the few commands, functions and syntax you needed to know.  The quantity of tools/frameworks/development environments currently available is awesome and fearful.

Thanks for reading
