why isnt this working? IF "!VV:~0,1!"=="%"

[nnnmmm]

Code: Select all

@ECHO OFF
SET K1=M:\AA.TXT

SetLocal EnableExtensions EnableDelayedExpansion
FOR /F "DELIMS=" %%V IN ('TYPE "%K1%"') DO (
   SET VV=%%V
   ECHO !VV:~0,1!

   IF "!VV:~0,1!"=="%" ECHO DDDDDDDD
)    
---------------------
AA.TXT has
%c1%\1.exe
%q1%\b.exe
ss.exe
dd.exe

why cant IF detect "%", while it echos correctly?
how can i solve?

The percentage sign is a special character that indicates that the following might be an environment variable.
In your case you are using the environment variable '" ECHO DDDDDDDD' (without the outer single quotes).
But there is a way to escape a percentage sign (== using a replacement string for this character): '%%'.

Code: Select all

   IF "!VV:~0,1!"=="%%" ECHO DDDDDDDD
