Must be an easy one - percentage sign in windows command line

I would like to pass the string "%24x" (without double quotes) to my application as a command line argument (usually referred as argv. I cannot on Windows7.

I tried the following:
> app.exe %24x
--> $x
> app.exe %%24x
--> %$x
> app.exe %;24x
--> %;24x
> app.exe "%24x"
--> $x (so quoting does not look to change anything)

So, how will a single percentage sign go through as an argument? How to do escaping?

Code:

---

"%"24x

---

worked for me :)

Great, it does
