Batch file IF variable?

Hi I am working on a small batch file on notepad

and I got a bit confused when it came to the IF variable here is my current notepad file:

(a small chunk)

set/a sum=2015-%year%

echo.

echo By the end of 2015 I guess your age will be %sum% %fname%

pause >nul

@Echo off IF %sum%=(12<>20)

echo (a teenager hey!)

ELSE

echo (Not in your teens are you?)

pause >nul

I know it is daft but its just a test file.

the problem is the screen is exiting even though ive paused it and I'm a bit unsure about the variable IF

any help will be useful hopefully.

 

Manipulating variables in batch files

When you read other people's batch files, you will see variables used in ways that seem peculiar & unintelligible.
- For Windows commands and batch files, variables are enclosed in % and sometimes %% [and you might sometimes even see %%%]
- You might see, and this is just for example, Set MyVar=%MyVar:*cd=% This does actually mean something and can be very useful. It is one of the examples explained below.
- Once you get the hang of manipulating variables in batch files you will be able to write very powerful procedures.
- Once you get the hang of manipulating variables in batch files you will be able to adapt very easily to manipulating variables in better structured scripting such as powershell.

This is a guide to manipulating batch files variables that I put together [based on a source whose identity I have rudely mislaid - it might have been RobvdW or an early version of Windows Batch Scripting - Wikibooks]
- Downloadable version ManipulatingVariables-UsefulExamples.bat.txt
- The file ManipulatingVariables-UsefulExamples.bat.txt is deliberately laid it out so it can be saved for reading as a text file [.txt] or for running as an innocuous batch file [.bat] - it is just a demonstrator, it displays variables onscreen but does not alter anything else at all. So it is safe to run. Just change its file extension for what you want on any given occasion [txt/bat] - no other changes are necessary.
- It pauses after every example so you can examine each one in sequence.

System environment variable won't stick

Running Win10 Home on an Acer Spin 3, 64bit, i7cpu. I try to add a path to the system environment variables by:

1. Control Panel > System > Advanced system settings > Advanced tab > Environment variables

2. The "Environment Variables" window opens.
3. In the "System Variables" pane I select "Path" and click the EDIT button.
4. A list of the current system paths is displayed.
5. I click the NEW button, browse to the path I want to add which is "C:\Python36-32" and click OK. The path "C:\Python36-32" is added to the list of current system paths.
6. I click OK and am returned to the "Environment Variables" window.
7. I click the "X" at the top right to close the "Environment Variables" window.

Now if I click the "Environment Variables" button again (end of step-1) and repeat steps 2-4, the new path I added in step-5 is gone. IOW, adding a new path won't stick.

What am I doing wrong?
