I reread the docs and I am still unclear with the code: $a[ 10 + rand( @a - 10 ) I do understand everything but $a[ 10 + rand( @a - 10 )
b/c you say subtract 10 from each element occurrance => @a - 10 then add 10 to the result of rand (@a - 10) To me this is offsets itself which is why I am confused. Will you explain again? I think you missed an explanation step between a and b? Reagardless it work so thank you. --- "D. Bolliger" <[EMAIL PROTECTED]> wrote: > Derek B. Smith am Donnerstag, 28.
