This gist shows the usage of batch parameters in a bat file and shows how to extract extra information about its location or its parameters.

batch-parameters.bat

SET BAT_FILE = %0
SET FIRST_ARG = %1
SET SECOND_ARG = %2
SET FIRST_ARG_WITHOUT_QUOTES = %~1
SET BAT_DRIVE = %~d0
SET BAT_PATH = %~p0
SET BAT_FOLDER = %~dp0

REM Suppose batch-parameters is located in C:\BatFolder\
REM When executing batch-parameters.bat "C:\First" "D:\Second"
REM the above variables will be set as follows

SET BAT_FILE = batch-parameters.bat
SET FIRST_ARG = "C:\First"
SET SECOND_ARG = "D:\Second"
SET FIRST_ARG_WITHOUT_QUOTES = C:\First
SET BAT_DRIVE = C:
SET BAT_PATH = \BatFolder\
SET BAT_FOLDER = C:\BatFolder\
