How many end keywords are there?

[357mag 2]

I thought in Delphi there was end; with a semicolon

 

And end. with a period

 

But I have seen a third end

 

That one has nothing after the keyword

 

What's going on?

The semicolon is optional after an end in some circumstances. Please see this. I know it's not after an "end" but the principle is still the same.

Semicolon is also forbidden before else...

[David Heffernan 2345]

Semicolon is the statement separator, and so is only needed if the next code is a statement

 

It's also only by convention that you put the semicolon right next to the end. You could equally write:

 

begin
  // foo
end                  ;

 

Same is true for the end of a unit. You can write it like this:

 

end               .

 

If you omit the period at the end of a unit the compiler error says

So, it's talking about the period which it considers a separate thing.

 

So, in conclusion, there's only one end keyword. And semicolon is the statement separator, unrelated to end. And the period marks the end of a unit. Again unrelated to the end keyword.
