Why Does My Dyalog Session Only Show File, Options, and Help?

This menu appears when Dyalog cannot locate your session file. When no session configuration is found, Dyalog loads a minimal default menu.

Why This Happens

Dyalog uses a session file (.dse) to define menus, preferences, and interface behaviour. If the session file cannot be found, has been moved, or has been deleted, Dyalog falls back to a basic menu.

How to Fix the Problem

Open Options → Configure → Session and check the Session file setting. Ensure it points to a valid .dse file.

Check the Current Session File Setting

+2 ⎕NQ '.' 'GetEnvironment' 'session_file'

If You Do Not Have a Session File

)load buildse
BUILD_SESSION 'UK'

Then save the session file using Session → Save As.

Available Session Templates

Summary

This behaviour indicates that Dyalog cannot find your session configuration. Restoring or creating a session file resolves the issue.
