The Command Shell (Option 6) provides users with a dedicated interface to execute TSO (Time Sharing Option) and CLIST/REXX commands directly from ISPF. This panel is essential for performing mainframe operations that are outside the scope of predefined ISPF menus and panels.

Key Features -

• Direct TSO Command Execution: Allows users to execute TSO commands without leaving the ISPF environment.
• Send files to Host: Sends the files from local computer to mainframe server.
• Receive files from Host: Receive files from mainframe server to local computer.
• Integration with CLIST/REXX: Enables running of CLIST (Command List) scripts and REXX (Restructured Extended Executor) programs.
• Enhanced Flexibility: Provides a command-line interface for complex operations, file management, job submission, and more.
• Immediate Results: Displays the output of commands or scripts directly on the screen.
• History Retention: Stores previously executed commands for reuse.
