Sure. For example there's BESEN, which is a complete implementation of the ECMAScript 5th edition standard. Programmed by a single person in Object Pascal.
My previous employer still has actively maintained PL/I in production. Anything is possible in the bowels of Corporate America.
Yes, I've seen Cobol, APL too... but pascal was not so much a language for business applications, except in delphi I guess.
There is definitely quite a bit of Cobol around on mainframes powering many mission-critical applications. Replacement of these old systems generates huge revenues for companies like Oracle/Peoplesoft and SAP.
Pascal was a great learning language. Probably second to BASIC, but much better as a precursor to learning C.
