Arrays need an Index to make them useful. I decided that if a button is clicked on, the number of this button will be put into a value which can be read by the program which is started by the Buttonclick. Sounds complicated, but I guess, this is the easiest way to do it and the easiest way to understand. Today I added this function , and the next step will be to clone the function of the first button to all other buttons of this array.
As a result this function has to be written only once, and depending on the number value of the activated button it can be executed differently or with different values. If you use a Button-Array as a numerical keypad, the number value of the button can be used just as the numerical value the button is intended to deliver. Easy, isn't it?
Today I had some other work to do, so the rest of it has to be postponed until tomorrow.
It seems to be we have springtime now: We do not have snow since two weeks and it was pleasant warm today, snowdrops are there since a week, and tulips are showing their first green tips. Squirrels are still feeding themselves on the birdseed.
