Can you elaborate on why you feel this reduces readability? I think it is a slight readability improvement: keeping the redundant "if" check suggests that the code is prepared to handle a NULL `name1', whereas that is not the case. By removing the "if", it makes the code's assumption (that name1 is non-NULL) more clear. A similar line of reasoning applies to the tab-complete change. As for "robustness in the face of future change", I don't see how it makes any difference. The code presently assumes that `name1' is non-NULL. If that changes, references to `name1' will need to be checked, but that is neither difficult nor unexpected if you change the range of values that can be assigned to `name1'. Or would you have us add redundant "if (var)" checks before using any pointer variable, on the principle that at some point in the future the code might change so that the variable could be NULL? -Neil
