compiled local variable Message #1 Posted by DK2ZA on 7 Oct 2009, 9:10 a.m. Hello all! I would like to write a HP-50g program containing a compiled local variable. Problem is: I do not know how to type that small left arrow which precedes the variable's name using the calculator's keyboard. Help would be appreciated. Greetings, Helmut

(Brazil) on 7 Oct 2009, 9:34 a.m., in response to message #1 by DK2ZA Hi; when you are keying in your program, press [right-shift][EVAL] and all existing characters will be shown in the display (scroll it down and up, if needed). This is a way to key any character in. Choose it (cursor keys) and press [ECHO]. Cheers. Luiz (Brazil) Edited: 7 Oct 2009, 9:35 a.m.

Re: compiled local variable Message #6 Posted by Vieira, Luiz C. (Brazil) on 8 Oct 2009, 1:10 p.m., in response to message #5 by David Hayden Hi, David; the right-arrow you get with the [right-shift][0] is not the same one you need for compiled local variables. The one that works here is the left-arrow, not available as a regular ALPHA character. Either you assign it to a key in the ALPHA keyboard (as Kiyoshi correctly suggested) or you use the CHARS menu. I first read about compiled local variables (I do not remember reading about them in original HP manuals) at James Donnely´s "The HP48 Handbook" (2nd. Ed, p. 46). I consider this one a 'must read'. I also do not know if Willian Wickes tells about them in his "HP48 Insights", third volume (HP48G) because I did not read it (yet). Hope this helps. Cheers. Luiz (Brazil)
