I am unable to figure out why the value is not stored in a variable in Windows 10. I search on the internet didn't get any reason why this not working.

@echo off
:start
REM check if there are more then one argumnets
if not "%2" == "" (
echo Too many parameters entered 
) ELSE (
REM check if argument one is empty
SETLOCAL ENABLEDELAYEDEXPANSION
if "%1"=="" (
echo "Enter your Name"
SET /P filename=
echo Your Name  is "%filename %" 
) 
if "%filename%"=="" (
echo "empty"
) else (
 echo "dat"
)
)

When I run this:

Enter your Name
asd
Your Name  is

Am I doing something wrong?

  • `"%filename %"` has to be `"%filename%"` (in fact, `"!filename!"`) – Stephan Apr 20 '19 at 18:15

This may also help you out:

@Echo Off
SetLocal EnableDelayedExpansion
If "%~1"=="" (
    Echo No parameter was passed
    GoTo EndIt
) Else (
    If Not "%~2" == "" (
        Echo Too many parameters entered 
        GoTo EndIt
    ) Else (
        Echo "Enter your Name"
        Set /P "filename="
        If "!filename!"=="" (
            Echo "empty"
        ) Else (
            Echo Your Name  is "!filename!"
            Echo "dat"
        )
    )
)
:EndIt
Pause
