Hey, im having some PROBLEMS finding how to overwrite multiple variables to 1 .bat file with mutiple lines. Basicly im making a small Rpg game and there is a few stats (e.g. strength, health, intellect) that i want to write to one file such as:
set strength=25
set health= 100
set intellect 50
within the main batch file im using the command echo set health=%health%>health.bat, but ideally i want to put all these variables into 1 file. This is where the problem comes in, any ideas how I would go about overwriting say the strength without affecting the others? I thought of using something like:
 FOR /F "tokens=2 delims=," %%G IN (stats.bat) DO echo %%G %%H
and having them laid out with in 1 line with commas separating each variable, but I still cant figure out how to use a command to overwrite the specific one needed and also set that variable into the main file (as I don't want to just echo it).

If there is any more information I have missed or if you need anything clarified just ask,
Thanks in advance.You have more tools available to you by using the WSH instead of just plain batch. Batch is so 1990 ish. It is so retro.
In the search box above enter WSH and find articles that have talked about this before.Well, you would probably have an easier time by reading and writing the stats at the same time. So this: Code: [Select]for /f "delims=," %%A in (stats.bat) do (
  set health=%%A
  set strength=%%B
  ...
)could be used to read your stats and a simple:
Code: [Select]echo %health%,%strength%,...>stats.batto write the stats back. It's easier to do it this way in batch, but as Geek suggested, you may have an easier time doing this in another language.Hey guys, thanks for the REPLY but I'm still having a little trouble with it, first off just wondering in your 2 codes Raven would the first 1 read MULTI line but the second one only save to single line? and when I try the code I get this:

and to reply to Geek-9pm i have never even heard of WSH and most of the game is already created im just working on loading/saving the game now, thanks for the tip though ill be looking it up Quote

Windows Script Host
From Wikipedia, the free encyclopedia
  (Redirected from WSH)
http://en.wikipedia.org/wiki/WSH

The Microsoft Windows Script Host (WSH) is an automation technology for Microsoft Windows operating systems that provides scripting capabilities comparable to batch files, but with a greater range of supported features. It was originally called Windows Scripting Host, but was renamed for the second release.

Thanks for the reply squash, but I need the stats to be overwritten rather than flooding the file with updated ones. Any idea how I could change your code to achieve this?
Thanks.

You obviously didn't run my code.  If you look at the output you will see after changing the values and rewriting the values to the stats file that the only values back in the file are the original value names with updated stats numbers.  I don't know what you are thinking it is doing.

Ahhh, I thought by "output" you meant what would be in the file after the code had run, my apologies and thank you again, Ill have a look into all suggestions and see what code fits best then.
