Random number 40-90

I have been looking for a batch who random chose a number 40-90, but I can't find any command who can specify a certain number. Why I want 40-90 is because I use 1-25 already and the 25-39 I made space if I'm going to use more numbers later.

Here is how I was thinking it should look like

Code: [Select]

echo off
cls

Echo Text

//The random number goes here.

If  '40' Goto '40'
If  '41' Goto '41'

//Here would the random number from 40-90 go.
:40
echo Text
GOTO start

:41
echo Text
GOTO start

:start
set /p var=

I'm still learning how to use all batch commands, I just know the basics of it, but I would be grateful if anyone have the knowledge how can help me.

I found this in the snippet closet. Just a few tweaks and it is made to order:

Code: [Select]

@echo off
setlocal

set intLowNumber=40
set intHighNumber=90

set /a rnd=%random% %% (%intHighNumber% - %intLowNumber% + 1)  + %intLowNumber%
echo Random number between %intLowNumber% and %intHighNumber% is %rnd%

FYI: use rem statements for comments; // are used in other languages, not batch

Good luck. 

Thanks for the help, but I got to a other bummer I'm trying to get that the random number it create it then will go to a number,

Code: [Select]

@echo off
cls
setlocal

set intLowNumber=40
set intHighNumber=90

set /a rnd=%random% %% (%intHighNumber% - %intLowNumber% + 1)  + %intLowNumber%
%rnd% ((<=If that number is 40 then)) GOTO 40
%rnd% ((<=If that number is 41 then)) GOTO 41

But every time I try to do that I get "GOTO was unaccepted at this time" and then it kill it self, I have tried different commands but it still wont work...

have you created the labels :40 and :41 for it to jump to ?

have you created the labels :40 and :41 for it to jump to ?

yes, I also have 40-90

Code: [Select]

%rnd% ((<=If that number is 40 then)) GOTO 40
%rnd% ((<=If that number is 41 then)) GOTO 41

Is this really part of your "code", Frejoh466? If so, I believe I know why your script keeps crashing.

since you have only just started, why not learn a programming language? A good programming language such as Python (and others) provides you programming concepts and constructs, such as arrays, hashes, dictionaries that every programmer should know and many more. Plus, it comes with modules/libraries that make programming easier and fun. Here's one way
to get random number in Python.

Code: [Select]

import random
random_number=random.randrange(100)
if random_number < 40:
    print "do something"
elif random_number<90:
    print "do something"   




Code: [Select]

%rnd% ((<=If that number is 40 then)) GOTO 40
%rnd% ((<=If that number is 41 then)) GOTO 41

That is not what my code look like, my code is kinda long so I only use the part that don't work so it wont be that long...

I'm trying to use that code in this part,

Code: [Select]

if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto unlock
if NOT EXIST Hide goto create
:lock
ren Hide "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
goto End
:unlock
echo Enter password to Unlock folder
set /p "pass=>"
if NOT %pass%==lol goto exit
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Hide
goto exit
:create
md Hide
goto exit

:exit
exit


note quote marks

Code: [Select]

if NOT "%pass%"=="lol" goto exit

note quote marks

Code: [Select]

if NOT "%pass%"=="lol" goto exit

But it work without the quotes.

But it work without the quotes.

Try pressing ENTER when it asks for the password.

Frejoh466, you changed scripts! First it was all that "goto 40" stuff, then all of a sudden you're trying to hide Control Panel! What's going on?

What do you think this line is going to do? (Line 6)

Code: [Select]

goto End

And this is why I only post the part that don't work... Ok forget my last post, I'm trying to use that random number the %rnd% create to go to the :40 or :41 etc.

so the number that %rnd% create it will goto

Hope this get through...

Whatever it is you are trying to do, I am quite sure that there is a better way. Probably involving fewer lines! The computed goto is heavily frowned upon by programming experts. However if that is what you want...

(You can change intHighNumber and put in the label sections from 51 to 90 yourself. Notice that you do not need goto end after the last number because you are going there anyway.)

Code: [Select]

@echo off
set intLowNumber=40
set intHighNumber=50
set /a rnd=%random% %% (%intHighNumber% - %intLowNumber% + 1)  + %intLowNumber%
goto %rnd%

:40
echo number=40
goto end
:41
echo number=41
goto end
:42
echo number=42
goto end
:43
echo number=43
goto end
:44
echo number=44
goto end
:45
echo number=45
goto end
:46
echo number=46
goto end
:47
echo number=47
goto end
:48
echo number=48
goto end
:49
echo number=49
goto end
:50
echo number=50

:end


Thanks for replaying and thanks for helping me out.
