Dear Gamma,
I happily used RPN for many years.....Why ? 'cause there was a time when a programming language called Forth ( a.k.a. FORTH ) was pretty darned well perfect for what I needed. Native Forth relied / required RPN
See more about it at
https://en.wikipedia.org/wiki/Forth_(programming_language)
While not as super slick as some of what is around today it was pretty darned good for the time. I have a recollection of a number of neat systems fitting easily in 32kb (ytes) with another 32kb for HD sector buffering
( you might be wondering about "kb". That means "kilo bytes". Its around one thousandth of a megabyte or one millionth of a gigabyte ).
I dont do any of that now..... 'cause these days I'm just a tired old fool
Y'all be good π
