Hi, I am planning to have a hash like 
   %hash = {g1 => [start_date1,end_date2]
            g2 => [start_date1,end_date2]
};

[download]
but i dont have a unique value of g1 and g2.. i will get unique value with combination of some values like value1 value2 value3 ..value5 so i planned to derive g with concatenation of these values assuming that a hash cannot have mutiple values of as a key. I thik the background is explained better now.

In reply to Re^2: can i concatenate various value to form a unique key by Anonymous Monk
in thread can i concatenate various value to form a unique key by Anonymous Monk
