ISPF

In computing, Interactive System Productivity Facility (ISPF) is a software product for the z/OS operating system that runs on IBM mainframes. It includes a screen editor, the user interface of which was emulated by some microcomputer editors sold commercially starting in the late 1980s, including SPFPC. ISPF is user-extensible and it is often used as an application programming interface. Many vendors have created products for z/OS that use the ISPF interface. ISPF can also be run from a z/OS batch job.
