On z/OS, openFT can be operated using so-called ISPF panels. For calling openFT functions via ISPF panels, the IBM program product "Interactive System Productivity Facility" (ISPF) must be installed on the system. ISPF provides a character-oriented user interface in the form of so-called "panels". The presentation corresponds to that of a 3270 terminal emulation, i.e. by default, 24 lines of 80 characters each. The example below illustrates a typical "start menu":
The panels make use of a menu and question-driven method with immediate feedback on errors and available help functions. The panels make it possible to use practically all the openFT functions that are also available via the command interface.
When the FT user uses this menu interface, the corresponding commands are issued internally.
