When output was longer than cmdheight, if you look at the sceen contents and the statusline in this situation, you'll see it's shifted upward in a manner that never happens during editing, essentially screen is corrupted.

For example, let cmdheight = 1 exe normal :echo\cr let cmdheight = s:tmp_cmdheight works when the statusbar has been pushed up a small number of lines. It seems to know how to recover without a full redraw. If it gets pushed up even more, then it fails to clear. The command also doesn't reflect the pushed position of the statusline, so there's no way to put a case for it in the script that way.

Not sure if it helps, but try this: :map ,x :let a=10CR and execute it by ',x' (no apostrophies) and then see for comparison this: :map ,x :let a=10CR/BS execute and see the difference. Is it something you were looking for? ---Zdenek

I never face this issue, as in all my maps, I try to avoid the output of commands appearing on the screen. Here are some techniques off the top of my head (you might find more if you search all my plugins, for maps): - Use silent where possible. - To execute functions on command-line, use C-R=func()CR instead of func()CR - When it is still necessary to clear the command-line, use :BS -- HTH, Hari __ Do You Yahoo!?
