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 KEY LABEL * KEYBOARD '{CTRL+0}' 
at the beginning of your program and dont forget to set it to default by giving ON KEY LABEL * at the end of your program.
