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.

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.
