scrolling/paging question

[Wayne]

I'm working with some wide files in vile. 600+ characters-per-line
with nolinewrap enabled.

If the cursor is positioned several hundred characters into a line I can
use the j/k keys to scroll through the lines without the screen
shifting. However if I use page-up/page-down/ctrl-f/ctrl-b/ctrl-u/ctrl-d
the cursor is re-positioned back to the beginning of the line.

I can use move-window-down/move-window-up with a count but it still
seems in some cases, which I don't quite fully understand yet, the
cursor is positioned back at the start of the line.

Is there a convenient way to page through wide files without the
cursor changing columns?
