Have you used your calculator for something that was not really math related?

I don't quite know if this is math-related or not, but here goes. One really simple thing I use my HP50G for is to keep a list of V1/Vr/V2/Vfr speeds in an array which I feed with table data, i.e. I look up the weight and flaps from a paper table, get speeds, put them into the array. Trying to automate that is considerably beyond me and my current programming skills on UserRPL (practically non-existent).

Does anyone have any suggestions for that? I've got all the relevant data, I'm even prepared to input the whole lot into the calculator, but what I don't know how to do is to correlate that for input values of weight, flaps, altitude and temperature. The way I would have done it in bash (a scripting language) would have been to create large arrays and simply report which value matches most closely. On a stack-based language, that's a bit more difficult.
