Hello All, There seem to be a double posting to the list of my question. Sorry for that and thank all of you who helped me solve my problem. Solution -------- {s1 -> -11, s2 -> 12} /. (x_ -> n_ /; n < 0) -> (x -> 0) {s1 -> 0, s2 -> 12} Regards, Ariel. -----Original Message----- From: Ariel Fligler [mailto:ariel.fligler at cellpay.biz] To: mathgroup at smc.vnet.net Subject: [mg32376] [mg32339] How To Change A Rule Greetings, I'm quite newby to Mathematica programming and will thank you if you could help me solve the following: I have a list of rules of the form: {s1->-11, s2->12} And would like to change every rule in the list that it's right hand side is negative to 0 so that I will get: {s1->0, s2->12} I tried to find an access function to manipulate rules but could not. Any help will be greatly appreciated. TIA, Ariel.
