if exit..

how do i make it so that if the ms-dos is exit that it will then start a file or a code?
and for this code here i would like it for when it goes to equ 1 and equ 3 how do i make it so that they goto a differnt secton

set /a var=%random%%%4



if %var% equ 0 set one=I like it cause of that to.
if %var% equ 1 set one=eww, are you sure?
if %var% equ 2 set one=Wow, never thought of that.
if %var% equ 3 set one=Are you sure?
echo %one%

the word 'sure' is spelt thus.

well if u want the code to exit to start another bat file then make another batch file, and then type the code like this on the first batch file

Code: [Select]

start <name of batch prog>
exitand then for the batch code above if u want it to goto different sections try this

Code: [Select]

set /a var=%random%%%4



if %var% equ 0 set one=I like it cause of that to.
if %var% equ 1 set one=eww, are you shurr?
if %var% equ 2 set one=Wow, never thought of that.
if %var% equ 3 set one=Are you shurr?
echo %one%
pause
goto %one%
then for the different sections make sure u type a colon before the label but there cant be any spaces in the label or else DOS will close the program. so try this to mark each section(this label will mark the "I like it cause of that to" section- :Ilike)
try the ":Ilike" label for that particular section make sure it has a colon and that there arent any spaces.

Code: [Select]

goto %one%

You can't do this. (Expand a variable to a label name & goto it)

ok...now try this

Code: [Select]

set /a var=%random%%%4



if %var% equ 0 set one=I like it cause of that to.
if %var% equ 1 set one=eww, are you shurr?
if %var% equ 2 set one=Wow, never thought of that.
if %var% equ 3 set one=Are you shurr?
echo %one%
pause
label %one%
goto one

From testing, I discovered you can in fact expand a label name go to it:

Code: [Select]

set  one=two
if errorlevel 0 goto %one%
goto :eof

:two
echo %one%

If you leave echo on you can see the expansion in real time. You cannot however expand a variable as part of a label:

Code: [Select]

set  one=two
if errorlevel 0 goto %one%
goto :eof

:%one%
echo %one%

 

label %one%

What does this line do?

PS Can we spell "sure" properly please?

So you can, I now see. I was always taught that self-modifying code is a bad idea, however.

I think that was what I was thinking of.

Amen Debugging such a beast can be a nightmare. Just because you can do something is no reason....

I'm still trying to figure out what the OP meant by if the ms-dos is exit

And somebody else needs to look up the label command...

Thus Spake Zarathrustra

Thus Spoke Z a r a t h u s t r a  (German: Also sprach Zarathustra, sometimes translated Thus Spake Zarathustra), subtitled A Book for All and None (Ein Buch für Alle und Keinen), is a work by German philosopher Friedrich Nietzsche, composed in four parts between 1883 and 1885. It famously declares that "God is dead", elaborates Nietzsche's conception of the will to power, and serves as an introduction to his doctrine of eternal return.

Described by Nietzsche himself as "the deepest ever written", the book is a dense and esoteric treatise on philosophy and morality, featuring as protagonist a fictionalized Zarathustra. The text encompasses passages of poetry and song, often mocking Judaeo-Christian morality and tradition.

well what i guess what im trina do is something like this .,.its not correct because i dont know what to do

if %var% equ 0 set one=I like it cause of that to.
if %var% equ 1 set one=eww, are you sure?
if %var% equ 2 set one=Wow, never thought of that.
if %var% equ 3 set one=Are you sure?
echo %one%
if if %var% equ 1 set one=eww, are you sure? goto h

:h
why do you think this?
set /p choice=



so like i want it that if the choice of if %var% equ 1 set one=eww, are you shurr? is picked i want that one to go to h and just that one.

how do i do that

if %var% equ 0 set one=I like it cause of that to.
if %var% equ 1 set one=eww, are you shurr?
if %var% equ 2 set one=Wow, never thought of that.
if %var% equ 3 set one=Are you shurr?
echo %one%
if if %var% equ 1 set one=eww, are you shurr? & goto h
goto skip

:h
why do you think this?
set /p choice=

:skip

correct

what that didn't work for me , when it got to the random part it just crashes on me.

Code: [Select]

set /a var=%random% %%4
                   ^
                   ^
                   ^
   needs a space here






didn't work for me.

What happened? You need to tell us more. Just saying "it didn't work" is not good enough if you want us to help you.

By the way, could you spell 'sure' properly please?

the batch file just exits , the code you gave me didn't work.

Are you running this batch file from the command prompt or are you double clicking it from Explorer? Until you have debugged your file, you should run from the command line so you can see how your code behaves.

 

i fixed it i had some problems with the goto stuff but its fixed now thanks for all the help really need it!
