FSI : Bind but do not display

Question

Issue

If I use let with a long array in fsi, FSI outputs a lot of data:

- let abc = System.IO.Directory.GetFiles("c:/Windows/System32");;
val abc: string array =
  [|"c:/Windows/System32\07409496-a423-4a3e-b620-2cfb01a9318d_Hype"+[21 chars];

Question

Is there a way to suppress the output for just that line?

Reasoning: Sometimes when I'm in VS Code (Ionide), I'll send a single line using alt-enter and it will output a lot of data as shown above. I then have to scroll back pretty far just to see previous lines. It would be nice to suppress the output for these kinds of let binding lines. If I want to see the output, I can always evaluate that name.

Comparison with PowerShell

If I assign a variable in PowerShell, the output is silent on the console:

PS C:\users\dharm\dropbox\documents> $abc = ls C:\Windows\System32
PS C:\users\dharm\dropbox\documents>

So that's the behavior I'm looking for with FSI.
