Re: Help with HP42S program input Message #6 Posted by Vieira, Luiz C. (Brazil) on 29 Mar 2005, 7:38 a.m., in response to message #1 by Dannyg77
Hi, Danny;
just to add that the PIXEL command (function) in the HP42S uses only two numbers as coordinates, so after the sequence: 475
1
476
-1
477
PIXEL PIXEL will actually use both (-1) and (477) as arguments. In fact, I'm not quite sure if negative values will cause the pixel to be off the display limit OR if only the integer part is used, meaning (-1) (477) PIXEL is the same as (1) (477) PIXEL. Also, after the very sequence you mention, (475) is lost without being used as argument.
Cheers.
