ISPF/PDF

Interactive System Productivity Facility/Program Development Facility (ISPF/PDF) is a programmers text editing environment for mainframe systems from IBM, while the editor itself has never been ported to any of the smaller systems the company made a number of tools that allowed people to work with the editor from PC based computers. Early versions were basically 3270-type terminal emulators that connected to a mainframe via a serial connection and offered some scripts to help with integration. Later a simple client server of sorts was offered by giving the terminal emulators simple file communication capabilities, a MVS program called IND$FILE handled file transfers and later you could also use the FTPB protocol.
