You should be able to get the calculator applet to do something like that, say with a 1 in the register and M+. At the end, use MR to get the final value.





Of course, there are mechanical, hand-held counters made for just that purpose.





Hope that helps.

void onButtonClick() {


counter++ ;


}





Actual implementation details for the button will vary depending on the GUI framework you are targetting.
