how create a wave with random string?

hi,ervery one,I'm a new IGOR user,I wanted to create a new wave with random string,so I could useing the string name to operate each row

For example

variable i
wave wave0
string w_temp
w_temp="wave0"
//Because I want to change the string of w_temp

$w_temp[i]=i //it error
I don't know if I exactly unerstood what you want want to do, but maybe this helps:
variable i
string str
str= "wave0"     // of course wave0 must exist as a wave
wave w= $str
w[i] = i
