Yes OK and "very long" would be?
It varies by country. In the case of the USA, 95 years from publication (for older works) Other countries employ the author's life+x years (usually 50 or 70)--live to a ripe old age and your copyright can run for a very long time.
In the USA, the rule of thumb is that you're generally safe with works published before 1923, which, I imagine does not include much computer software.
