I've not yet trained in scripting.
What does echo do?
How do you use each echo and &
How do you decide when to use ()

Echo: Print messages in standard output.
&: chain individual commands
(): They are used to group commands to also decide the order of execution in the pipe (|) and where to send the output for all commands. If you don't use them, only the last command in the pipe is sent.

I'm also not an expert but I made the first batch raytracing a long time ago but I forgot a lot. Google "raycast dos batch"

For readability you can change it to this which inserts the result in the system clipboard

Code:

( 
  Echo Lis Dis
  Echo sel dis 1
  Echo lis par
  Echo sel par 1
  Echo assign letter=U
  Echo lis par
  Echo lis vol
  Echo Exit 
) | DiskPart | clip

Write the output into a file on the desktop.

Code:

(Echo Lis Dis
 Echo sel dis 1
 Echo lis par
 Echo sel par 1
 Echo assign letter=U
 Echo lis par
 Echo lis vol
 Echo Exit)|DiskPart > %UserProfile%\Desktop\Output.txt
