On the CL (or V41 in turbo mode) it's obtained in the blink of an eye. I'm positive my implementation isn't earth-shattering or novel-prize material Dieter, I just wanted to have a reliable TVM$ added to the SandMath on the 41 platform - using MCODE. So I wrote it from the scratch, not copied from the 12C or anything. Besides the i% solver it also has a very nice U/I that mimics the 12C design almost to the last detail, with alphanumeric characters for the results. I guess what I'm saying is that it works for me and hopefully also does for other folks. Naturally will be nice to improve it, say implement the counter idea: how many loops are too many and where would you put the cut-off point?
