Microsoft Windows XP [Version 5.1.2600]

C:\>choice /?
CHOICE [/C[:]choices] [/N] [/S] [/T[:]c,nn] [text]

/C[:]choices Specifies allowable keys. Default is YN
/N           Do not display choices and ? at end of prompt string.
/S           Treat choice keys as case sensitive.
/T[:]c,nn    Default choice to c after nn seconds
text         Prompt string to display

ERRORLEVEL is set to offset of key user presses in choices.

ok, 2 questions
how would define your default choice?
and
what is errorlevel? (i've seen it quite oftenly in batch files)

ok, 2 questions
how would define your default choice?
and
what is errorlevel? (i've seen it quite oftenly in batch files) 

Example

Default choice is Y, timeout is 10 seconds

Code: [Select]

choice /C:YN /T:Y,10 Press Y or N
echo errorlevel is: %errorlevel%

If Y was pressed (or timeout occurred) the %errorlevel%  will be 1 (because Y is choice 1) and if N was pressed %errorlevel% will be 2 (because N is the second choice)

errorlevel is a system variable which is set by a program. Often 0=no error, 1 or more means an error. Choice uses it to pass the key pressed.

Code: [Select]

S:\>chtest1.bat
Press Y or N [Y,N]?Y
errorlevel is: 1

S:\>chtest1.bat
Press Y or N [Y,N]?N
errorlevel is: 2

[PirateSamir]

so can errorlevel be used for anything else?

[Dias de verano]

so can errorlevel be used for anything else?

Yes.

Code: [Select]

dir *.txt
if %errorlevel% GTR 0 echo "No text files"

Plenty of information if you use Google.

ok thnx

[ht]

Code: [Select]

@ECHO OFF

:choice
set /P c=Are you sure you want to continue[Y/N]?
if /I "%c%" EQU "Y" goto :somewhere
if /I "%c%" EQU "N" goto :somewhere_else
goto :choice


:somewhere

echo "I am here because you typed Y"
pause
exit

:somewhere_else

echo "I am here because you typed N"
pause
exit

Thanks hiteshsavla - Exactly what I required, saved me a lot of time.  (I write batch files so infrequently these days that it takes time to get back into it)
