Apparently Simula doesn't allow variables to be initialized in their
declarations.  Because of that, `n := inint;` (where inint is actually a
call to a value-returning procedure) is a separate statement.  If
Simula supported C-style initializers, then presumably the inner block
would not be needed:

    begin
        integer n := inint;
        integer array arr (1:n);
        arr(5) := 9;
    end
