PASCAL vs EPASCAL. Different things.

Ignore Wikipedia in this instance, use the Fine Manual
(these words from 1985's VAXELN V2 Pascal Language 
Reference Manual, courtesy of Bitsavers):
"VAXELN Pascal is a compatible superset of the 
language defined in the International Standards 
Organization document ISO DIS 7185. Any program 
written in ISO-standard Pascal can be compiled 
by the VAXELN Pascal compiler and executed as 
part of the system. 

However, VAXELN Pascal has been extended to 
include data types and operations that support 
concurrent programming. (continues)"

VAXELN was designed around a different compiler 
and runtime than the usual VAX Pascal setup.


Meanwhile, while I'm here, if I may attempt 
to summarise some aspects of the language 
discussion so far:

Oh hang on, Prince was/is a project management thing, not
a programming language. 

Speaking of details, and changing the topic somewhat, 
Windows may not have VMS-style RMS, but for the last 
decade or so (Win7?) Window boxes have had a versioned
file system under the hood. 

Not everyone who changes files on a filesystem is a 
developer (etc) with all their working practices built 
around revision control systems, and for those people 
and those operations, a file system with versions can 
be quite a handy thing. It's well hidden, so it may 
not be widely known. But the capability is allegedly 
there. Is the capability robust and trustworthy? 
Different question entirely.
