Although my problem is now solved, I still would like to understand it - and perhaps spare others a few hours. When using Curve_bspline(sourceCrv,destCrv) to fit a spline to some data and then plot destCrv, everything went well. But then I added some further processing of destCrv, and the results seemed to implicate, that destCrv was not changed by Curve_bspline. But still it plotted fine in the test. Finally (after hours :-( ) I added destCrv.Update(TRUE) and suddenly it worked! Does this mean, that Curve_bspline does not actully work as an OriginC command but is instead invoking a LabTalk command without updating the OriginC copy of the curve?
