Interesting. (I didn't know that DEC supported a Pascal dialect.)

WRT that comment; I think that {...} is not worse than the (*...*)
variant we often see. - The main point is, though, how it fits in
the language. - "C" is already full of punctuation characters, and
especially the '*' is existing in many contexts. Pascal, OTOH, is
very text-biased; so its two comment variants don't annoy [me] too
much. (The "open end" comment property is not dominating here.)

What's that '$' preceding the function names? (I don't recall that
from the Pascal standard or from the versions I programmed with.)
