Re: echon space ?
redrawing doesn't help. In this case with getchar(), echon'ed trailing spaces are only shown after a non-space character is echon'ed afterwards. It's not a big deal, but I'm going to cc: [EMAIL PROTECTED] since I can't find any way to create a getchar() + prompt with trailing spaces. I'm writing mappings like: cnoremap cd call Cd_plus() such that I want the user to see ":cd " as the prompt in the command line.

It's getchar() that's eating up trailing spaces. Compare @a's for: :redir @a | echon " 123" | call getchar() | redir END :redir @a | echon "\n123" | call getchar() | redir END :redir @a || echon " 123" | call getchar() | redir END Not sure what the last example is supposed to do. The "\n" or previous ex command "|" has something to do with it. (tested on Vim 6.3) -- Gerald It's odd that it remembers all the trailing spaces, and prints them out as soon as the echon following the getchar() prints a non-space char. I'm thinking that it could also be the rendering in the command window that is causing it, as if it truncates trailing spaces when writing to the screen, but not when actually building the strings internally. It's probably a combination of this, and that getchar() isn't in the list of things that triggers printing the trailing spaces. I can't tell whether to call this a bug yet. (Just guessing in the dark) Could it be a redraw problem? Best regards, Tony.
