---------------------  SHIFT - Internal Batch Subcommand  ----------------------

SHIFT allows a batch file to make use of more than ten replaceable parameters
   entered on the command line.

FORMAT:   SHIFT

REMARKS:

   There are ten replaceable parameters, numbered %0 - %9.  More than ten
   parameters may be used by "shifting" them.  SHIFT moves each parameter on
   the command line one position to the left, so that %0 becomes %1, %1 becomes
   %2, and so on.  Subsequent SHIFTs continue to move parameters one position
   lower.

EXAMPLE:

The following batch file, ECHOIT.BAT, echoes (displays) the values of
replaceable parameters, SHIFTs them, and echoes their values again.  The default
drive is A:

          ECHO %0 %1 %2 %3 %4 %5 %6 %7 %8 %9
          SHIFT
          ECHO %0 %1 %2 %3 %4 %5 %6 %7 %8 %9
          SHIFT
          ECHO %0 %1 %2 %3 %4 %5 %6 %7 %8 %9

Invoking the batch file with:

          ECHOIT 1 2 3 4 5 6 7 8 9 10 11

produces:

          A>ECHO ECHOIT 1 2 3 4 5 6 7 8 9
          ECHOIT 1 2 3 4 5 6 7 8 9

          A>SHIFT

          A>ECHO 1 2 3 4 5 6 7 8 9 10
          1 2 3 4 5 6 7 8 9 10

          A>SHIFT

          A>ECHO 2 3 4 5 6 7 8 9 10 11
          2 3 4 5 6 7 8 9 10 11
