%random% seems to go in order.
@ECHO OFF
SET /A RAND=%RANDOM% %%100
ECHO %RAND%
ECHO.
If you keep running this it increments until it reaches 100 and then the number start over. If it were random it would jump around.
@ECHO OFF
SET /A RAND=%RANDOM%
ECHO %RAND%
ECHO.
SET /A RAND=%RANDOM%%%100+1
this may work.
If I understoof the question right, here's what you're looking for.
echo off
title Number from 1 to 100.
color 0a
cls
:loop
cls
set /a rand=%random% %%101
echo %rand%
pause >nul
goto loop
hey if the problem still persists
use this code
this generates a number between a and b
tweak it to your needs
@echo off
color 02
echo enter value of A
set /p a=
echo.
echo enter value of B
set /p b=
:main
set no=%random%
if %no% GEQ %a% goto sub
if not %no% GEQ %a% goto main
:sub
if %no% LEQ %b% goto end
if not %no% LEQ %b% goto main
:end
echo %no%
goto main
