How to create a batch file that accepts two integers as parameters

Question

I am just beginning to learn command line scripts, and I have an assignment for school in which the first part is to create a batch file that accepts two integers as parameters. The integers will be subsequently manipulated throughout the question, and I am not looking for any help with that. I have googled this many different ways, and cannot seem to come up with an answer. How do I begin this?

I know this is very basic to probably everyone that reads this, but I am asking you to cut me some slack, we all have to start somewhere.

Answer 1

On windows, it is %1 %2

http://commandwindows.com/batch.htm

example:

@echo off

echo %1 %2

set /a v = %1
set /a v2 = %1 + 1
set /a v3 = %1 * 2

echo %v% %v2% %v3%

Answer 2

Assuming this is Windows, you can reference the parameters in your script as %1 and %2.

Answer 3

Assuming MS-DOS, you can use %1, %2, etc. for input parameters.

@ECHO OFF

SET /a INT1=%1
SET /a INT2=%2

SET /a ANSWER=INT1*INT2

ECHO %ANSWER%

PAUSE

You could then call this as:

mybatchfile.bat 2 4

Answer 4

If the requirement of your assignment doesn't specifically say you definitely must use batch (cmd.exe), you can use vbscript. It has a tad better error handling, and can do floating point maths etc, better than what cmd.exe can offer.

On Error Resume Next
num1= CInt(WScript.Arguments(0))
num2= CInt(WScript.Arguments(1))
total=num1 + num2
If Err.Number <> 0 Then
    WScript.Echo "Description: " &  Err.Description
    Err.Clear
Else
    WScript.Echo "Added: " & total
End If

example

C:\test>cscript //nologo assigment.vbs 1 2
Added: 3

C:\test>cscript //nologo assignment.vbs 1 test
Description: Type mismatch
