Ok I've completed my testing finally. It turns out that the solution to my problems is simpler than I ever would have thought. It appears that the problems I've had with the Save[] command not faithfully saving real numbers only affects version 3.0. When I run the following code in version 3.0, it never takes long before the loop exits indicating that what was saved by Save[] does not match what was read back in. However in version 4.2, try as I may I could not get the loop to terminate. So that's it, I can just re-save all my real numbers in 4.2 using the Save[] function then read them in from my 5.2 instance. Thanks again for everyone's input (and especially Chris for giving me the idea to re-test the Save[] function)! Terry P.S. Here's the code I used for testing: x = True; While[x, targetFunction = 537932*Random[Real,{1,27}]^3; targetFunction2 = targetFunction; Save["temp",targetFunction2]; Clear[targetFunction2]; Get["temp"]; DeleteFile["temp"]; x = RealDigits[targetFunction2,2] == RealDigits[targetFunction, 2]; If[x == False, Print[RealDigits[targetFunction,2]]; Print[RealDigits[targetFunction2,2]]; ]; ];
