Well, one that I worked with was ICL QuickBuild, which was used by a few
hundred mainframe users in the UK for generating transaction processing
applications (some of them massive applications).
I remember it although I never understood it. There was also
ApplicationMaster... didn't understand that either.
It actually had many XSLT-like characteristics (which is what attracted me
to XSLT when I first encountered it).
Hah if only I knew then what I know now.
A program was a declarative description of an entire user session, with
all the management of session state taken care of behind the scenes. There
were quite a few such languages - most, like this one, tied to particular
hardware and software environments. Software AG's NATURAL is another
example.
I used to be an ADS/Online programmer - Cullinet Software IDMS database.
I don't think any 4GL had more than about 3% of the market, and that's
mainly what killed them - no standards, no critical mass.
They were all proprietary and restricted to 1 hardware manufacturer. Then
along came relational databases, open systems and PC's.

I would like to think that the only thing that will lead to XSLT's
decline is when someone invents something better, and there's no sign of
that on the horizon. This might be wishful thinking, however; there were
some excellent special-purpose languages in the 1980s that didn't survive
because they didn't have a viable user and developer community, despite
being ideally suited to their task
Like for example?
