[RESOLVED] batch: IF ELSE STATEMENT

[vietboy505]

IF ELSE STATEMENT

Since there is no else statement in Batch script. How do I by pass that?

I want this script will ask for a name if the name doesn't match the input.
The name will be hardcode, so the person who run it doesn't enter his/her name everything. It just goes directly to check status right away and print out the message.

Why this not working the way I want it?
This will goes through all command even though I try to put in JOHN or DAVE.

How can I covert the user input to all CAPS or the variable %NAME% to all CAPS?
---------

@ECHO OFF
SET NAME="ENTER_NAME_HERE"
GOTO :START_MENU

:START_MENU
IF %NAME% == "ENTER_NAME_HERE" GOTO :ASK_MENU
:END


:ASK_MENU
SET /P NAME="ENTER NAME: " GOTO :CHECK_MENU
:END

:CHECK_MENU
IF %NAME% == "JOHN" GOTO :JOHN_MENU
IF %NAME% == "DAVE" GOTO :DAVE_MENU
:END

:JOHN_MENU
ECHO YOUR NAME IS: %NAME% HAVE A NICE DAY!
:END

:DAVE_MENU
ECHO YOUR NAME IS: %NAME% PEACE OUT!
:END

PAUSE

thanks for the help..

Sorry to tell you but there is no way to change cases in just plain DOS.

You might want to try it in VB Script. You can use Visual Basic commands to convert the case, and use IF-THEN-ELSE statements.

You can simulate IF ELSE statement like this:

@echo off

set answer=one
if not "%1" == "1" (
   set answer=two
   if not "%1" == "2" (
      goto bad_argument
   )
)

echo Argument %1 is %answer%
goto end


:bad_argument
echo Bad Argument

:end

There is indeed IF-ELSE syntax in batch. This works for me, but you have to be sure to use it exactly as shown:

IF <statement>  (
..
..
) ELSE (
...
...
)

I believe the parentheses must be used exactly as shown above, or the statement won't work properly.

I have not, however, found a nice way to handle ELSE-IF statements. So, you have to make big nested IF blocks:

E.g.
IF <statement> (
IF <statement> (
...
) ELSE (
...
)
) ELSE (
...
)

One annoyance I've noticed is that assignments (i.e. SET statements) made within an IF block are not realized until AFTER the IF-bock. So, in other words, you can't rely on variable assignment within an IF-block.

A way to use an IF ELSE IF statement is simply nest the ELSE IF

IF <arg> (

....


) ELSE (

IF (

......

)

......

)
