Win XP Pro SP3, TCC 11.00.40 I discovered quite accidentally that a command with a leading question mark (but not a single isolated question mark) asks the user whether to execute the command. E.g., > ?foo foo (Y/N)? Y TCC: Unknown command "foo" > ?echo food echo food (Y/N)? Y food > ?echo drink echo drink (Y/N)? N (nothing) This works if the command is in a .bat or .btm file, too. I have no alias named "?". I couldn't find anything in the help file about it (but that just may be because I didn't know how to look it up). Rex, is this a feature?
