remote administration, such as Distributed Host Command Facility (DHCF), which allowed a Host Command Facility (HCF) user on a mainframe to log on in either full-screen mode or line mode to execute commands as though logged on locally, and Distributed Systems Network (or Node) Executive (DSNX), which allowed a Distributed Systems Executive (DSX) (later NetView/DM) job to manage files. Separate additional products were also available, including COBOL and Fortran compilers, the Distributed Transaction Management System (DTMS), Command Facilities Extensions (CFE), which provided easy support for full-screen applications, Data Stream Capability (DSC) to allow DPPX users to log on to applications on the mainframe, and Performance Tool (PT).
