Hi, I have a large set of values like this in two different columns,both the values are variables..
I need to check if first value(ValA) is same in any of the consecutive values and then find the difference between valB of those two matched valA! and the next instant the difference should be between the valB of second one with third match. For example in this set, 9 appears thrice. first time, the difference shd be printed as 3099 - 3000, the next time, it should be printed as 5098 - 3099. valA,valB 9,3000 10,3010 1,3011 2,1020 3,3001 4,4010 9,3099 5,4011 18,4020 19,2044 20,3098 9,5098 How do I do this in Perl?? regards venkat. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
