How to get the path of a batch script without the trailing backslash in a single command?

Question

Suppose I wish to get the absolute path of a batch script from within the batch script itself, but without a trailing backslash. Normally, I do it this way:

SET          


        

Answer 1

Only with delayed expansion when you write both statements into the same line:

set BuildDir=%~dp0&&set BuildDir=!BuildDir:~0,-1!

But that kinda defies the purpose.
