Hi Jamie,
It is a program for school- and test evaluation. I need the null value in the calculations!!! because there must be a difference between a zero result and not made the test or absent. So in the grid all tests of all the students start with a null value represented by an asterisk in the grid. When the teacher writes down the results, it may happen that he is mistaken and that he writes down a result on the place of an absent student. He will try to restore the asterisk, but the computer does ntot accept the asterisk (certainly not as a null value) he has to use CTRL+0. The null value is really very useful for my calculations!!!

On the other hand they start often using the program without reading the manual. Because of the simplicity of the program this is not a major problem except for this null value. They try the asterisk but this has no effect of course, they should use CTRL+O. That's why I prefer the real asterisk as the keystroke for the null value.
