Store a sentence in a variable (batch) - windows

Question

I am making a batch file, and whenever their is a user input field, which the user enter a word or a sentence and it get stored in a text file. I made all the job done.
But when the user's input is more than 1 word, it gives the following error:
*second word* was unexpected.
How can this be solved?
#echo off
color f0
:menu
cls
echo Batch Editor
echo Choose what you want to do:
echo 1) New Document
echo 2) Load existing document
echo 3) Learn How to Use
echo 4) Exit
set /p menu=
if %menu%==1 goto new
if %menu%==2 goto load
if %menu%==3 goto learn
if %menu%==4 goto exit
if [%1]==[] goto learn
echo Invaild Code
pause
goto menu
:new
cls
echo You have chosen to start a new document.
echo But please note that is impossible to know how to code
echo without seeing the "How to Learn" section.
echo Choose:
echo 1) Continue anyways
echo 2) Go to the "How to Learn" section
echo 3) Exit
set /p type=
if '%type%'=='' goto new
if %type%==1 goto newdoc
if %type%==2 goto learn
if %type%==3 goto exit
echo Invaild Key
pause
goto new
:newdoc
cls
set /p input=
if %input%==Qsave goto saving
if %input%==qsave goto saving
if %input%==qSave goto saving
if %input%==QSAVE goto saving
goto newdoc1
pause
:newdoc1
set /p chosen=
if '%chosen%'==''(
goto newdoc2)
else if "%chosen%"=="Qsave" (
goto saving)
else if "%chosen%"=="qsave" (
goto saving)
else if "%chosen%"=="qSave" (
goto saving)
else if "%chosen%"=="QSAVE" (
goto saving)
else (
goto newdoc2)
:newdoc2
set /p chosen=
if '%chosen%'==''(
goto newdoc1)
else if %chosen%==Qsave (
goto saving)
else if %chosen%==qsave (
goto saving)
else if %chosen%==qSave (

:saving

Answer 1

You really should post what you currently have, if all you're trying to do is store user inputted text to a text file, something like this might help?
SET /P Answer=Say somthing witty!
ECHO %Answer%>Response.txt

Answer 2

set var=Alpha beta Gamma
if %var%==whatever
is translated to:
if Alpha beta Gamma==whatever
IF Syntax is IF <Argument1> <comparator> <Argument2> <command>
Argument1 is Alpha, Comparator is beta - wait, this is wrong...
It leads to "beta was unexpected", because there should be a compatator (==), not an Argument.
Better Syntax:
if "%var%"=="whatever"
is translated to:
if "Alpha beta Gamma"=="whatever"
Argument1 is "Alpha beta Gamma", Comparator is ==, Agrument2 is "whatever" - fine Syntax.

Answer 3

Sample menu where there are only three possible choices plus one covering mistype:
#echo off
:retry
cls
Unset the variable M
set M=
If nothing typed, then set M to 4
SET /P "M=Type 1 for pizza, 2 for soup or 3 for exit, then press ENTER: " || set "M=4"
Here we use variable substring. See http://ss64.com/nt/syntax-substring.html
IF [%M:~0,1%]==[1] goto pizza
If M are not set to 1, then go to the next line, etc...
IF [%M:~0,1%]==[2] goto soup
If M are not set to 1 or 2 then check if it's set to 3, there is the last IF statement, we can now use else to cover everything else in the variable M
IF [%M:~0,1%]==[3] (
echo Bye...
#timeout /T 1 /nobreak >NUL
exit /b 0
) else (
goto :retry
)
:pizza
echo Pizza
goto :EOF
:soup
echo Soup
goto :EOF
Edit: My if statement was a bit redundant, see the revision history to see what I mean.
