String with spaces in set /p (batch file)

Hi! I would like to let a user type in things with spaces in set /p. This is the code I currently have that does not work:

Code:

:newdoc2
cls
echo What do you want to say?
set saynew=%randomnum%
set /p saynew=
if %saynew% == %randomnum% goto newdoc2
echo "%saynew%" >%namenew%
goto start

This works if saynew has no spaces, but not if it does. If I type, for example, "hello people", it will briefly say "hello was not expected at this time" and then crash. What did I do wrong? I tried putting "" around %saynew%:

Code:

echo "%saynew%" >%namenew%

but it did not work. Any ideas?

If you need the whole thing, here it is:

Code:

@echo off
title Text Reader
color 17
goto start
set randomnum=%random%

:start
cls
title Text Reader
echo Type the location of the file and the filename. Type "end" to close, or type "new" to make a new document.
set /p file=
if %file% == new goto newdoc
if %file% == end goto end
if not exist %file% goto start
goto main

:main
cls
title %file%
type %file%
echo.
echo (End of Document)
echo Press any key to go back to start...
pause >nul
goto start

:newdoc
cls
title New Document
echo Type a name, and location if necessary.
set namenew=0
set /p namenew=
if %namenew% == 0 goto newdoc
:newdoc2
cls
echo What do you want to say?
set saynew=%randomnum%
set /p saynew=
if %saynew% == %randomnum% goto newdoc2
echo "%saynew%" >%namenew%
goto start

:end
exit
