Re: Any C++ regex template class gotchas?

Charles, Do you get fed up with having to specify the pesky tr1 namespace? It makes it difficult to share code between z/OS and distributed. You can work around that with a useful namespace declaration. Also, if you are using LANGLVL(EXTENDED0X) you can significantly cut down on the verbosity

Edward, Here's the basic process: 1. Order and receive physical DVD media containing the software products, via postal mail or courier. 2. Insert the DVD into the drive of any machine that your designated z/OS LPAR can reach. (Not necessarily *every* z/OS LPAR.) That machine might be the HMC

Thanks, but won't work well in the real code. I have multiple instantiations of the same class, and don't know the pattern until well after the instantiation. Pattern may change after instantiation. It doesn't take much to make it work. The std::tr1::regex::flag_type flags =
