hey.. i have made a random number gen it creates a random number from 1 to 5 i was wondering if anyone knows a way i could use this to pick a random letter from a string? set string=abcdefg somehow i need to get a single character from this string. here is the number gen. @echo off SET C=10 set times=0 :loop :more if %times% equ 5 goto :done set /a times=%times%+1 set /a R=%random:~-1% if %R% gtr %C% goto :loop if %R% lss 1 goto :loop set /a rnd%times%=%R% if %times% LSS 5 goto :more :done echo %rnd1% %rnd2% %rnd3% %rnd4% %rnd5% pause thx genet

Didn't work for me. ========================= C:\temp\-\multserv\strlen\rndchar>g 5 9 1 C:\temp\-\multserv\strlen\rndchar>g 3 4 9 1 8 C:\temp\-\multserv\strlen\rndchar>g 3 8 7 2 5 C:\temp\-\multserv\strlen\rndchar>g 9 7 7 3 7 C:\temp\-\multserv\strlen\rndchar>g 1 7 8 7 7 C:\temp\-\multserv\strlen\rndchar>g 6 4 9 6 8 ===================================== If at first you don't succeed, you're about average.

Hi Genet Just learning to program are we. Not the way I usually program but might help with your logic. The !r! is simlar to %r% The times=+1 is the same as times=%times%+1 The list= ABCDE The first position is 0 not 1 but as the numbers are 1-5 this position is never used. Have fun. @echo off setlocal EnableDelayedExpansion set List= ABCDEF :again set times=0 :loop set r=%random:~-1% if !r! GTR 5 goto loop if !r! LSS 1 goto loop set /a times+=1 set /a rnd!times!=!r! if !times! LSS 5 goto loop echo [%rnd1%] [%rnd2%] [%rnd3%] [%rnd4%] [%rnd5%] echo !List:~%rnd1%,1! !List:~%rnd2%,1! !List:~%rnd3%,1! !List:~%rnd4%,1! !List:~%rnd5%,1! pause goto again

Hi dtech10, Yeah, yours works. As you say the positions start at 0. You can eliminate the space and use positions 0 thru 4. And you can simplify by using a mod 5 instead of range checking. ::==Rchar6.bat @echo off setLocal EnableDelayedExpansion set str=ABCDE set /a P=!random!%%5 echo !str:~%P%,1! ::==================== ===================================== If at first you don't succeed, you're about average.

Hi Mechanix Thanks for that. I used the values 1-5 as that was what he wanted, much more elegant used modulus.
