How to use random in BATCH script?

Represents a replaceable parameter. Use a single percent sign ( % ) to carry out the for command at the command prompt. Use double percent signs ( %% ) to carry out the for command within a batch file. Variables are case sensitive, and they must be represented with an alphabetical value such as %a, %b, or %c. ( <set> )
The random number or a range of random numbers can be generated using the $RANDOM variable. It generates a random number between 0 and 32767 by default. But you can set the range of numbers for generating random numbers by dividing the value of $RANDOM with a specific value.
To generate random numbers in C#, use the Next(minValue, MaxValue) method. The parameters are used to set the minimum and maximum values. Next(100,200); We have set the above method under Random() object.
%RANDOM% gives you a random number between 0 and 32767.
Using an expression like SET /A test=%RANDOM% * 100 / 32768 + 1, you can change the range to anything you like (here the range is [1…100] instead of [0…32767]).

%RANDOM% gives you a random number between 0 and 32767.
You can control the number's range with:
set /a num=%random% %%100 - will produce number between 0~99.
This one:
set /a num=%random% %%100 +1 - will produce number between 1~100.
