part two of stringparsing.bat problems

Ok so everything's working with my stringparsing.bat program, i can successfully create, encode, and display the text files. However now the problem arises that it will not decode the the text file after encoding it. Say if the encoded text file contains:

20 18 1 9 14 19

When i decode it using this script:

@echo off
cls
echo.
echo.
echo.
echo.
echo.
echo        Decoding Your Language File... Please Wait... 
echo.
echo.
echo.

for /f "delims=" %%i in (!name1!.txt) do ( 
set var1=%%i 
set var1=!var1:1 =a ! 
set var1=!var1:2 =b ! 
set var1=!var1:3 =c ! 
set var1=!var1:4 =d ! 
set var1=!var1:5 =e ! 
set var1=!var1:6 =f ! 
set var1=!var1:7 =g ! 
set var1=!var1:8 =h ! 
set var1=!var1:9 =i ! 
set var1=!var1:10 =j ! 
set var1=!var1:11 =k ! 
set var1=!var1:12 =l ! 
set var1=!var1:13 =m ! 
set var1=!var1:14 =n ! 
set var1=!var1:15 =o ! 
set var1=!var1:16 =p ! 
set var1=!var1:17 =q ! 
set var1=!var1:18 =r ! 
set var1=!var1:19 =s ! 
set var1=!var1:20 =t ! 
set var1=!var1:21 =u ! 
set var1=!var1:22 =v ! 
set var1=!var1:23 =w ! 
set var1=!var1:24 =x ! 
set var1=!var1:25 =y ! 
set var1=!var:26 =z !
set var1=!var1:27 =. !
set var1=!var1:28 =, ! 
echo        Verifying Content...

) 

echo %var1% > %name1%.txt
echo Decoding Complete!

TIMEOUT /t 1 /nobreak > nul

I get:

t 1h a i 1d 1i

Because when the program decodes the letter r (which is 18) it mistakes the 8 in 18 for the letter h and therefore puts 1h... so is there a way to make it a specific search and replace? (similar to if your typing a path to a file with spaces in it,you would put quotes around the path and file name) If so what would the format be?

EDIT Heres the current script for the stringparsing.bat program:

I get:

t 1h a i 1d 1i

Because when the program decodes the letter r (which is 18) it mistakes the 8 in 18 for the letter h and therefore puts 1h... so is there a way to make it a specific search and replace? (similar to if your typing a path to a file with spaces in it,you would put quotes around the path and file name) If so what would the format be?

Aha, you got the problem. And you see the cause. The 18 is replaced by the line

set var1=!var1:8 =h !

before the correct line can replace it

set var1=!var1:18 =r !

If you can't solve the problem, then there's no room for hope. :-)
