I agree that that would work but it's still wrong in principle IMHO i.e. then the regex is still a pseudo/meta regex i.e. it requires processing to turn it into a valid regex. This would have to be duplicated in all the different implementations etc.etc. Adam *********************************************************************** This message may contain confidential and privileged information.
