Batch file which saves user input path with spaces to a text file. (win 7) - input

Question

First of all i am a noob in programming.
I am trying to make a batch file which takes an installed directory of a program as user input when run for the first time (means it should not ask for the directory the second time it is run). By searching for various scripts, i reached till here,
#echo off
Echo =============================================
echo Directory
Echo =============================================
setlocal enableextensions enabledelayedexpansion
set /p mypath=Please specify install directory;
Echo %mypath% ----was what you typed
pause
echo start>temp.txt
echo %mypath%>>temp.txt
echo \programfolder\program.exe>>temp.txt
echo -argument -argument>>temp.txt
setlocal enabledelayedexpansion
set FINAL=
for /f %%a in (temp.txt) do (
set FINAL=!FINAL!%%a
)
echo %FINAL%>input.txt
del /q temp.txt
Pause
start "<input.txt"
This saves the input path in the "input.txt" text file, and runs the program the next time it is launched.
I want the text file to have the saved path as "start driveletter:\foldername\foldername with spaces\programfolder\program.exe" -arguments
However the "start", "program folder", "program.exe" and "-arguments" are fixed.
The user input path should get saved in- %mypath%.

The does what you asked, I think:
#echo off
if exist "go.bat" go.bat
set /p "mypath=Please specify install directory; "
Echo "%mypath%" ----was what you typed
pause
>"go.bat" echo #start "" "%mypath%\programfolder\program.exe" -argument -argument
