Batch file : comparison number

[sourpet]

Hi Forum users,
I am currently writting a batch file but I'm stuck... My batch file creates a text file and adds numbers

So for example I have numbers.txt and in it I have :
654
256
233

How do I make my batch file compare line 1 to line 2 or line 1 to line 3 ?

Please explain exactly what you are trying to achieve? What OS are you using? You may have gone past what you can do with batch files, and you may need to get into scripting.

Sorry,

I am using Windows 7, here's my program so far :
:wieght
echo Your weight in Kg :
set /P weight=
echo !weight! >>weight.txt

So here a dude will enter every day his weigth and I'd like to make an option " Compare your first day (first weigth) to your last one AND/OR your previous weigth to your new one.

Any help needed.

You are going to need to use some programming to do what you want to do. This will get you started: http://en.wikipedia.org/wiki/Windows_Script_Host
