About 3 days ago I asked a question, which can be found here:
how to replace a string on the second line in a text file using a batch file?
I'm converting the letters in a text file into their respective numbers. I'm getting error messages such as "Access denied" and "Cannot locate this file" -- but the same batch file that's giving me all these errors is also the one that made these text files to begin with! So it should be in the same directory as the batch file itself (unless specified otherwise), right? I even went to that folder and checked, and they're there.
I did add a small script to hide the files after they were created so that it wouldn't look so cluttered up. I did this by using
attrib +h C:\script\%name%.txt
Would hiding a file with this command make it invisible to batch programs that are searching for it/call upon it?
Here's a link to the file, "stringparsing.bat": http://uploading.com/files/a1m1d2f4/stringparsing.bat/
If you could assist me in getting this program to carry out its task without any errors it would be greatly appreciated!
Here's the "stringparsing.bat" file in full:

You've got a few problems. First, the access denied problem is from you redirecting to a hidden file.
echo %name% > Language_File.txt
attrib +h Language_File.txt
Note that the first time you run the script, it will work because Language_File.txt won't exist and therefore won't be hidden. The second time you run it, you'll get access denied. I don't know why Windows doesn't let you do that. You can solve this problem in a couple ways.
1. Save your file to the user's temp directory. With this approach your directory won't get cluttered.
echo %name% > %TMP%\Language_File.txt
2. Save your file to a subdirectory that you own so that it doesn't clutter the script's directory.
if not exist workspace mkdir workspace
echo %name% > workspace\Language_File.txt
3. Unhide the file before you use it. Since the file may not exist the first time you run the script, perhaps you should only attrib -h if it exists.
if exist Language_File.txt attrib -h Language_File.txt
echo %name% > %TMP%\Language_File.txt
attrib +h Language_File.txt
4. Don't use Language_File.txt at all! I don't see why you need it. Just use variables to hold the name of the language file. In fact, you already have the name in %name%, right?
Second, you should check the value of your variables to see what they really hold. When you load the contents of Language_File.txt into your variable, it's loading all the contents. That includes the hidden newline characters \r\n, although the script seems to bring them into the variable as spaces. See:
c:\batch\t>echo language file is loading now!
language file is loading now
C:\batch\t>set /p name= <Language_File.txt
C:\batch\t>echo -%name%-
-langfile -
If you echo %name% surrounded by hyphens, you can see that there are 2 spaces after it from (presumably) the newline characters. To solve this problem, you can use set to trim the trailing characters.
C:\batch\t>echo language file is loading now!
language file is loading now
C:\batch\t>set /p name= <Language_File.txt
C:\batch\t>set name=%name:~0,-2%
C:\batch\t>echo -%name%-
-langfile-
In the second example, `%name% doesn't have the hidden characters.
Finally, you only need to use ! to access variables that you set inside the for loop. So all references to !name! should be %name% instead. That's probably your "cannot find file" error.

I Finally learned how to format the code snippet. (heres a link to another copy of it if you need it.)
