\c user_var(destination) str [maxlen] [start_offset]
|
|
|
|
Sets the user variable $x with str. str can contain variables (including the user variable being set (concatenating strings this way is possible, etc)). If maxlen is specified, the string will be a maximum of maxlen characters (if maxlen is negative, the string will be truncated abs(maxlen) characters from the end). If start_offset is specified, the source is offset by it (if start_offset is negative, it will start abs(start_offset) from the end of the string).
