How can i reuse variable set in a FOR /f ??

[Yannick Ambert]

Hello,

i have wrote this batch file and the result is not good :

for /f "tokens=1" %%a in (.\list3.trc) do (
set NAME=%%a
echo %NAME%
pause)

the file list3.trc contain program names.
Why the echo %NAME% doesn't return all the program names ??

the execution result is :

FOR /F "tokens=1" %a in (.\list3.trc) do (set NAME=%a & echo &
pause)

(set NAME=dudley_editinv & echo & pause)
ECHO is on.
Press any key to continue . . .

(set NAME=dudley_inventaire & echo & pause)
ECHO is on.
Press any key to continue . . .

Please help me...

NOTA : I don't want to simply display the name but i want to make task
with this name.....
I know that the following file work fine :
for /f "tokens=1" %%a in (.\list3.trc) do echo %%a

NT processes a command line by expanding all environmental variables
BEFORE executing the line. That means that if you set a variable and
then try to echo that variable on the same command line, then the
value that will be echoed is the value of the variable as it was on
the previous command line. If the variable wasn't set, then you'll see
the message that you're seeing: ECHO is on. One workaround for this is
the following command line.

for /f "tokens=1" %%a in (.\list3.trc) do (
set NAME=%%a

for /f "tokens=2 delims==" %%b in (
'set^|findstr/b /i "name="') do echo %%b
pause)

Another way is

for /f "tokens=1" %%a in (.\list3.trc) do call :sub
goto :eof

:sub
set NAME=%%a
echo %NAME%
pause
goto :eof

I see from using the pause that this is going to be an interactive
script. This makes speed a non-issue. However, if you need this to run
in a non-interactive mode, you'll find the following to be
significantly faster. Just remove the pause and time it.

Bennett Benson

for /f "tokens=1" %%a in (.\list3.trc) do call :sub1 %%a
goto end
:sub1
set NAME=%1
echo %%b
pause
goto :eof
:end
