hp 39gii lcd clear question Message #1 Posted by giancarlo on 17 Aug 2013, 11:29 a.m. Hello, I know that you are all playing with the Prime. As usual I am a step behind and still playing with my (real) hp39gii. I wrote a simple program that creates, for each loop iteration, a number and display it via the 'print' command. When the program ends the stack is empty. If i run the same program twice, i can still see the results of the first run of the program and the new ones. It seems it is a kind of stack which is different from the one available for calculation which is not cleared at each program run and cannot be cleared via the 'rect()' command like a grob. If i switch off the calc, this stack is empty like a kind of garbage collection. Any idea of the command i can use to clear the stack? It is possible i didn't install last firmware so please apologize for not being up to date. Thanks Giancarlo from Italy (training for the prime)

Unfortunately the 'print()' command without argument(s) doesn't work on my calc. I think it is a matter of firmware. Would you mind telling me where i could find the last 39gii firmware? Thanks Giancarlo

Re: hp 39gii lcd clear question Message #6 Posted by giancarlo on 18 Aug 2013, 6:59 a.m., in response to message #5 by Mic No way. As soon as i write PRINT(); or PRINT; in my program, i got a sintax error. If i comment the line (inserting a double slash // before the print command), the program run flawlessly... Any idea? Thanks Giancarlo
