When was Pro-iv born ?

I seem to remember a copyright splash somewhere (PDP-11? V1.2?) that referred to "Data Technical Analysts" or something very similar and an associated date in the '70s. Could be wrong though...
Mr Crossdale will probably be able to put us straight if he's reading this

The ALL product was launched by Microdata about 1982/83 time. This was ProIV for Pick computers (specifically the Reality variant). Two of the Microdata consultants (Jerry Lees & Frank Strelau) formed a software house called Northgate to build systems in the 'new' language. This is where I learned my stuff (along with the learned gentleman who posted the previous comments!). Ironically - this is how MDIS ended up being called Northgate... but that's a long story.
I certainly heard the Hawaii story. As well as selling the source to Microdata, Sushil also sold the source and rights for a Unix version to C.Itoh. In theory this would have prevented a Unix version of ProIV from ever being produced - apparently the fact that C.Itoh called their version of Unix something different gave enough 'wiggle' room to claim that a generic Unix version did not fall under this license!
I also heard the Sushil previously created something called NoCode which was the precursor to ProIV. DTA (Data Technical Analysts) owned the original rights.

I tend to agree with the last post,

The local var sold quite a few systems to small governments, and I had a hand in developing enhancements to some of the modules.

Searching for proiv turned up this page- http://users.rcn.com...any_history.htm (what's with the dots in the link?)
In the 1970's Sushil Garg, the original designer and author of PRO-IV, was working as an applications programmer in Hawaii. There he experienced the traditional problems associated with developing and running computer applications systems.
The initial funding of the design and creation of PRO-IV was from Data Technical Analysts based in Reno, Nevada who in turn licensed the technology to three main licensees: Microdata (later acquired by McDonnell Douglas), C. Itoh and Pro Computer Sciences (PCS).
The European market was developed by distributors until Pro-Lab Plc. was established in May 1985, as a sister company to PCS Inc. A head office was set up in Cambridge with regional offices in Birmingham and London. Pro-Lab Plc. held exclusive rights to market and support PRO-IV in Europe, Hong Kong and China, Middle East and South Africa, and distributors were established in the majority of these territories.
In 1987 McDonnell Douglas decided to use PRO-IV as a main development tool. To develop its portfolio of system development products, as well as safeguarding its investment in internal software, in the December of that year it purchased the PRO-IV product from Pro Computer Sciences and Pro-Lab
I have no idea what the parent site is, but it's quite an interesting page and there's some other info hidden away there too.
The closest I found to an index for it is: http://users.rcn.com...roduct_home.htm
It looks like it might be some saves of an early version of the PROIV site as it's very similar to the description at at http://www.proiv.com...about/about.xsp
Searching for Sushil Garg lead to here http://www.gdis.com/sushil.htm and another pair of dates:
So there are hints that 1975 is significant in the timeline, but that PROIV was born around 1982
Sushil Garg has been a visionary player in the technology industry since 1975. Garg founded Pro Computer Sciences (PCS) in 1982, where he created the PRO IV development language. PRO IV was the first object-oriented, fourth-generation language to bring open architecture and real-time programming to business application development. Garg sold PCS in 1987 to McDonnell Douglas Information Systems, after which he started a thriving PRO IV consulting services organization.

This raises another question: why did they remove the object-oriented feature?
Posted 07 April 2004 - 06:18 AM
Object oriented is always a relative term. Based on what was around in the 70's, things like global logics and function structures certainly could have qualified as object oriented design.
Based on today's standards, the early versions of ProIV would not qualify.
But, it's not really fair to judge technology from 30 years ago with today's standards.
Posted 07 April 2004 - 09:16 AM
The 'original' object oriented language is usually taken to be Simula '67 (yes, 1967) although they didn't call it object orientation then I think. I don't think ProIV then or now could qualify as object-oriented by any objective (ho ho) criterion.
See also the bottom of this page:
(especially you green-screen fans).
Incidentally , the long-lost origins of a cerain major ProIV financial application were indeed in 'NoCode' on Data General.
(No points for not even having heard of Data General - read 'The Soul of a New Machine'.)
