@alexandros The idea is to print out numbers without repetition. Your idea is so much more advanced that I am not even going into that yet hehe

@whale-av Thank you so much - you have no idea how helpful it is. I understand that [b] is so much more different as it doesn't send any number, while [f] does, correct? I mean that was the whole problem with my little patch.

Yet, I am uploading other modifications, which I do want to understand - maybe you'll be interested, too? 1 working - 2 not working.pd It basically is the same patch with 3 different versions, which I cannot understand why the 1st is working and other 2 do not.

I am asking this (and annoying everyone in the forum with this stupid questions) because as I do not understand it, I am afraid to proceed further with studying. Or perhaps I am too paranoid and should just let it be and what I know is sufficient enough?
