<code>%RANDOM%</code> gives you a random number between 0 and 32767.

Using an expression like <code>SET /A test=%RANDOM% * 100 / 32768 + 1</code>, you can change the range to anything you like (here the range is [1…100] instead of [0…32767]).

blocks|key|919687|text|您可能希望获得多个随机数，并且可能希望能够为每个随机数指定不同的范围，因此您应该定义一个函数。在我的示例中，我使用call:rand+25+30生成从25到30的数字。在该函数退出后，结果在RAND_NUM中。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|919688|@echo+off+&+setlocal+EnableDelayedExpansion

You'll probably want to get several random numbers, and may want to be able to specify a different range for each one, so you should define a function. In my example, I generate numbers from 25 through 30 with <code>call:rand 25 30</code>. And the result is in <code>RAND_NUM</code> after that function exits.

<pre><code>@echo off &amp; setlocal EnableDelayedExpansion

for /L %%a in (1 1 10) do (
 call:rand 25 30
 echo !RAND_NUM!
)

goto:EOF

REM The script ends at the above goto:EOF. The following are functions.

REM rand()
REM Input: %1 is min, %2 is max.
REM Output: RAND_NUM is set to a random number from min through max.

SET /A RAND_NUM=%RANDOM% * (%2 - %1 + 1) / 32768 + %1

where <code>max</code> is your max and <code>min</code> is your minimum. This is not very efficient since might take a lot of rounds if your range is too small. Also, this will not work for numbers larger than 32767.

Let's say you want a number 1-5; you could use the following:

<pre><code> :LOOP
 set NUM=%random:~-1,1%
 if %NUM% GTR 5 (
 goto LOOP )
 goto NEXT
</code></pre>

Or you could use :~1,1 in place of :~-1,1. The :~-1,1 is not needed, but it greatly reduces the amount of time it takes to hit the right range. Let's say you want a number 1-50, we need to decide between 2 digits and 1 digit. Use:

<pre><code> :LOOP
 set RAN1=%random:~-1,1%
 if %RAN1% GTR 5 (
 goto 1 )
 if %RAN1%==5 (
 goto LOOP )
 goto 2

 :1
 set NUM=%random:~-1,1%
 goto NEXT

 :2
 set NUM=%random:~-1,2%
 goto NEXT
</code></pre>

You can add more to this algorithm to decide between large ranges, such as 1-1000.

here is a example i created for you, it should display a dialog asking you to select a number 1-10, depending on the number you select, it will generate a random number example to a batch file that you named. If you select "1" then you will get a random 1 digit number example. if you select "10" then you will get a random 10 digit number example.

<pre><code>@echo off
color f0
set /p "FileName= Enter Filename (Without Extension) : "
echo @echo off &gt;&gt; %FileName%.bat
echo File Created!
pause
cls
:CommandLine
set /p "calc= ~%ComputerName%: Enter a number to recieve the amount of random digits :"
if %calc%==genrand_help goto GenerateRandomHelp
if %calc%==1 echo echo %%RANDOM:~-1%% &gt;&gt; %FileName%.bat
if %calc%==2 echo echo %%RANDOM:~-1%%%%RANDOM:~-1%% &gt;&gt; %FileName%.bat
