change default version

[Phil Last]

I've asked this question before but can neither remember nor find the answer.

The user command ]FileAssociations appears to be what I need but

      ]fileassociations -???
─────────────────────────────────────────────────────────────────────────────── 
                                                                                
]MSWIN.FileAssociations                                                         
                                                                                
Change the file associations of Dyalog workspaces, applications and scripts     
(.dws, .dyapp and .dyalog files)                                                
    ]FileAssociations                                                           
                                                                                
NOTES:                                                                          
    ∘  Only users with administrator access can use this user command.          
    ∘  This command is only relevant if you have multiple versions of Dyalog    
       installed and want to change the version in which .dws, .dyalog or .dyapp
       files open when double-clicked on.

doesn't help a lot.

I've had to revert to an older machine as I've damaged my laptop screen. It's forcing v16.0 while I currently need v18.0 which is the latest installed in it.

OK. Ignore my question accidentally answered by hitting enter on the bare command.
