In the 90ies, Pascal had a lot of traction here in Europe. Turbo Pascal was the default language to use for DOS programming. I remember from my physics department that any computer-controlled devices came with Turbo Pascal units for controlling them. And later on, Delphi had its success, I guess it was more killed by bad management then anything else.
Interestingly, Go picks up a lot of Pascal (and of course Modula) tradition, as Robert Griesemer worked with Wirth before. A lot of the Wirth language family's ideas made it into Go clothed into a C syntax.
It had lots of traction in the 80's up to the late 90's, with Turbo Pascal being the most successful compiler in use, up to when Borland decided to go berserk and scare everyone away with their lack of focus on how to do business.
