RE: What is file manger and changeman little elaborate...
Don't know about the file-manager - are you asking about the one which comes up with Window? If you get answer please tell me too.Changeman is a Change and version control software for Mainframe - by Serena. Gives the standard Change control facilities like bundelling together the related components (programs jcls etc.) in a release (into a package) version conrol of individual components (release / rollback) and also gives a standard method of compilation....somthing similar to Alchemist (which i used a long while ago).
