Parameter passing and setting

Parameters passed when the batch is called:

DOS does not have the "Allow 9 batch parameter information" limit, the number of parameters is only limited by the command length and the processing power of the invoked command. However, we can only reference 10 parameters at the same time in a batch program, because DOS only gives the%0~%9 10 parameter references.

Create a file named Test3.bat, which reads as follows:

@echo off

IF "%1" = = "A" ECHO XIAO

IF "%2" = = "B" ECHO TIAN

IF "%3" = = "C" ECHO XIN

If you run:

C:\>test3 A B C

The screen will show:

XIAO

TIAN

XIN

If you run:

C:\>test3 A B

The screen will show

XIAO

TIAN
