I have again another question, is there a way to append arroys [..] inside UserRPL programs automaticly (=without dumping the arroy to stack and remaking it with new values)? Ie. for collecting values in loop structures to be used later. The arroy will not be declared at the beginning to final size. I know how to do it with lists {..} (+ command Smile ), but seem to not find a way (atleast for now) to do it with arroys. {[a b] [c d] ... [n m]} atleast might work with some post processing.
Also is there a "null" value that can be used in arroy as other datasets like NOVAL is used in some menu related stuff.

For arrays, I think you are looking for the COL+ and ROW+ commands, depending on how you want your array organized, each pair could be a row for example, which you can append with ROW+.
But in many cases, it's just more convenient to leave your results in the stack until you have the very last one, then you can make a list or an array (only once) at the end of the program.
Remember you have an infinite stack, which you can access with PICK/UNPICK and ROLL/ROLLD, and adding an element is as easy as leaving it there.
