[Gretl-users] about regsub()

Hi, the regsub function doc says: "Arguments: s (string) match (string) repl (string) Returns a copy of s in which all occurrences of the pattern match are replaced using repl. The arguments match and repl are interpreted as Perl-style regular expressions." But 'repl' cannot be a regular expression, it has to be a literal string which can be plugged in, right? Otherwise I don't see how it can work, or at least I cannot get it to work... thanks sven
