hi, thanks for ur reply,
I almost got it but here in this example which one is the hash and key and its corresponding values can we do without using IO::file and FH because here i have some values which are stored in an array and have to store those values to a key and also the important thing is am getting values dynamically at run time so for this first I have to chech whether the key exists or not if exists replace those values with the existed values.
For this thing, here am not understanding how to do this.
