There is no practical limit to the number of parameters you can pass to a batch file, but you can only address parameter 0 (%0 - The batch file name) through parameter 9 (%9).

To circumvent this behavior, you can use the SHIFT command, as in the following example:

test a b c d e f g h i j k l m n o p q r s t u v w x y z 0 1 2 3 4 5 6 7 8 9

where test.bat might contain:

@echo off
@echo %0
:again
if \{%1\}==\{\} goto :EOF
@echo %1 %2 %3 %4 %5 %6 %7 %8 %9
shift
goto again

With the above parameters, test.bat would display:

test                              a b c d e f g h i                              b c d e f g h i j                              c d e f g h i j k                              d e f g h i j k l                              e f g h i j k l m                              f g h i j k l m n                              g h i j k l m n o                              h i j k l m n o p                              i j k l m n o p q                              j k l m n o p q r                              k l m n o p q r s                              l m n o p q r s t                              m n o p q r s t u                              n o p q r s t u v                              o p q r s t u v w                              p q r s t u v w x                              q r s t u v w x y                              r s t u v w x y z                              s t u v w x y z 0                              t u v w x y z 0 1                              u v w x y z 0 1 2                              v w x y z 0 1 2 3                              w x y z 0 1 2 3 4                              x y z 0 1 2 3 4 5                              y z 0 1 2 3 4 5 6                              z 0 1 2 3 4 5 6 7                              0 1 2 3 4 5 6 7 8                              1 2 3 4 5 6 7 8 9                              2 3 4 5 6 7 8 9                              3 4 5 6 7 8 9                              4 5 6 7 8 9                              5 6 7 8 9                              6 7 8 9                              7 8 9                              8 9                              9
