Need help with a .bat Tags: Windows XP Last response: August 10, 2011 4:04 PM in Windows XP Share xGhost4000x August 10, 2011 2:06:05 PM Hello, I need to make a program which draws a random number 1-3 twice, but doesn't allow for duplicates. Here is what I have: Quote:echo off cls :begin~! set /a count=count+1 set /a pool=3*%random%/32768+1 echo %pool% if %count% == 2 goto !stop! goto begin~! exit :!stop! set /a count=nul pause goto begin~! As you can see that will pick 2 numbers out of a random num 1- 3, however currently there is nothing to stop it from drawing duplicates. Is there anyway to stop duplicates from being echo'ed ? Thanks! More about : bat Emerald August 10, 2011 4:03:28 PM can you use another variable that you assign the first number to and compare it to the second one drawn. if the two numbers are the same reduce count by one to run the randomization again if the second number is different display and exit AntiZig August 10, 2011 4:04:40 PM add an if statement that checks if its a duplicate, if it is go to step for number generation Can't find your answer ?
