Perhaps the issue is the phase of the moon on Mondays? Seriously, how do you expect anyone to offer constructive suggestions when you've provided no details of the function or package. It would be trivial for me to create a function in a package that behaves as you describe. For example, I could do something like the following: call SeedRandom[0] to set Mathematica's random number generator to a known state before defining the function, then defined a function such as func[x_,y_]:= x+y+Random[] Or if I wanted to be a bit more unpredictable I might have a counter to count the number of times the function is called and have calls made to Random[] whenever the counter reached certain values. Note, none of the above is likely useful or relevant to your specific problem. It merely points out the difficulty of providing constructive, relevant suggestions when you don't provide details of the problem you are having. -- To reply via email subtract one hundred and four
