Why the initial `echo`, when you can include it in the prompt string itself? 1. `:GetName`, 2. `@Set "name="`, 3. `@Set /P "name=What is your name?>"`, 4. `@If Not Defined name GoTo GetName`, 5. `@Echo Hello %name%`, 6. `@Pause`. – Compo Sep 15 '21 at 18:23

See what happens with your code if the user enters `& call dir "%UserProfile%\Desktop" /B /S & rem ` with a space at end. This code is not secure. It works on user inputs something expected by the author of the batch file. But I know people who enter a string containing `&` or other characters with special meaning for command processor on asking for a name because they want to be funny and enter a string being an emoji. The last command line should be at least `if defined name setlocal EnableDelayedExpansion & echo Hello !name!^^!& endlocal`. – Mofi Sep 15 '21 at 18:37
…or `:LOOP`, then `set /P name="What's your name? " || goto :LOOP`, then `echo Hello %name%!`… – aschipfl Sep 16 '21 at 09:05
