Simple batch script starting adb not working on Windows

Question

I would like to simply start adb with following script commands. I am not able to do. Can someone help?

set adbstart = C:\Users\username\AppData\Local\Android\sdk\platform-tools\adb
%adbstart%

output is:

set adbstart = C:\Users\username\AppData\Local\Android\sdk\platform-tools\adb

that's all. I expected the help page from adb.
