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 RHS 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 ? TIA, Ariel. Thanks, Ariel Fligler
