Yep.

%0 corresponds to $0, and the magic letters behind the tilde are explained (for example) here.

Nifty! And I wish I'd known all that back when I was using Windows!

@setlocal
@set thisdir=%~dp0
@set thisfile=%~f0
@set thisfilebasename=%~n0
@set thisfilename=%~nx0
@set thisfilecorion=%~dpn0.pl
@set thisfilepl=%thisdir%%thisfilebasename%.pl
@echo          thisdir=%thisdir%
@echo         thisfile=%thisfile%
@echo thisfilebasename=%thisfilebasename%
@echo     thisfilename=%thisfilename%
@echo   thisfilecorion=%thisfilecorion%
@echo       thisfilepl=%thisfilepl%
@echo;
@endlocal

         thisdir=D:\
        thisfile=D:\this2.bat
thisfilebasename=this2
    thisfilename=this2.bat
  thisfilecorion=D:\this2.pl
      thisfilepl=D:\this2.pl

And the advanced broken version (for stupid paths )
^ is trickier than the others ... above escaping useful for example if you're  echo %stuff% >> otherfile.bat
yes, cmd.exe is a mess

$  "D:\pa^th\this2.bat"
         thisdir=D:\path\
        thisfile=D:\path\this2.bat
thisfilebasename=this2
    thisfilename=this2.bat
  thisfilecorion=D:\path\this2.pl
      thisfilepl=D:\path\this2.pl

FWIW the second output was wrong one

$ "pa^th\this2.bat"
         thisdir="D:\pa^th\
        thisfile="D:\pa^th\this2.bat
thisfilebasename="this2
    thisfilename="this2.bat
  thisfilecorion="D:\pa^th\this2.pl
      thisfilepl="D:\pa^th\this2.pl


$ echo D:\path\this2.bat
D:\path\this2.bat
escaped-thisfile "D:\pa\^th\this2.bat"
