回答1:

Does this meet your "no extra file" criterion?

It's a batch file that creates and deletes a tool to get the input, and so it is completely portable, and works in 64 bit machines too.

Herbert Kleebauer wrote the utility and source code can be found on Usenet.

It requires Vista and later I think.

You can do like this :

EDIT :

  @Echo Off  
  :HInput    
  SetLocal DisableDelayedExpansion
Echo Enter your Code :
   Set "Line="
   For /F %%# In (
   '"Prompt;$H&For %%# in (1) Do Rem"'
   ) Do Set "BS=%%#"

  :HILoop
   Set "Key="
   For /F "delims=" %%# In (
   'Xcopy /W "%~f0" "%~f0" 2^>Nul'
   ) Do If Not Defined Key Set "Key=%%#"
   Set "Key=%Key:~-1%"
   SetLocal EnableDelayedExpansion
   If Not Defined Key Goto :HIEnd
  If %BS%==^%Key% (Set /P "=%BS% %BS%" <Nul
   Set "Key="
   If Defined Line Set "Line=!Line:~0,-1!"
   ) Else Set /P "=*" <Nul
   If Not Defined Line (EndLocal &Set "Line=%Key%"
   ) Else For /F delims^=^ eol^= %%# In (
   "!Line!") Do EndLocal &Set "Line=%%#%Key%"
  Goto :HILoop

  :HIEnd
   Echo(
Echo Your code is :  "!Line!"
   Pause
   Goto :Eof
