How to prevent re-display of Post Form after submitting it

Using edit-form-advanced.php (heavily edited) as part of a custom script to submit posts.
Problem: After submitting a blog post, the submission form reloads. How do I stop this, and instead re-direct to another page after submission?
There must be a line in edit-form-advanced.php that does this, but not able to find it even after lots of editing.
