close(file); always necessary??

[leledumbo]

Why rely on implementation? One good coding practice is to close what you've
opened. AFAIK in most Pascal implementation, even if the OS will close the
file upon program exit, the buffer that contains something you write will
not be flushed. So you will lose everything you've written.
