Not sure whether this is a bug.

Not according to the language definition.

It should be "VAR n : LONGINT; BEGIN" The semicolon is nt an end of line 
statement. It is a Start-Of-Line statement. In this case it signals the 
"BEGIN" coming up.

In the case of the END statement, things are different in that the END 
is known to come up; a LOOP is always concluded by an END. So the last 
statement in a LOOP/END does not need a ';' since the END was expected.

In your VAR case, the BEGIN cannot be predicted so the ';' is required.
