SHIFT
Type: Internal (2.0 and later)
Syntax:
SHIFT
Purpose: Increases number of replaceable parameters to more than
the
standard ten for use in batch files.
Discussion
Usually, you can only enter up to ten parameters at the time you start a
batch
file (%0 through %9). Use this command to shift the assignable
parameters to
make room for the use of additional entries.
For more information on using the SHIFT command and other batch commands,
refer
to Chapter 5, Using Batch Files.
Example
If you started a batch file named GO.BAT by entering the following on the
command line:
go X1 X2 X3 X4 X5 X6 X7 X8 X9 X10
the parameters available for use in the batch file GO will be set as
follows:
%1 = X1
%2 = X2
%3 = X3
%4 = X4
%5 = X5
%6 = X6
%7 = X7
%8 = X8
%9 = X9
To use the additional parameter you entered on the command line (X10),
enter
shift
The parameters will be reset as
%1 = X2
%2 = X3
%3 = X4
%4 = X5
%5 = X6
%6 = X7
%7 = X8
%8 = X9
%9 = X10
The set parameters are shifted one higher, giving you access to more than
ten
parameters. Each time you enter the SHIFT command, the parameters used
by the
batch file are shifted up one position.
