Why do you want to do this? What good will having an unknown number of different variable names do you? How will you access them? How will you know how many there are? Use arrays and hashes to hold collections of things, not separate scalar variables. > I have looked over the camel and lama > books but am not > exactly what I am looking for, "dynamic array variables"? > > I am looking for some assistance here, and what to keep this > as dynamic as > possible, and want to be able to refer to the variable > contents later in the > script if need be ( this is the whole point of the matter ).
