Re: Quadratic & Cubic Regression RPN progs Message #8 Posted by Jeff O. on 17 Sept 2013, 9:17 a.m., in response to message #7 by Matt Agajanian
Matt,
I believe the "\" (back-slash) symbol is some sort of "escape" character that the original author used to format the program listing. It is not a command or part of a command to be entered into the calculator. So wherever you see the backslash, just take it out. So your questioned lines would look as follows:
36 |-" [x,y]LF-> Y, na"
37 |-"t# order -> x .."
41 |-"d inLFvars SIGMADAT"
etc.
The "|-" is the append symbol, entered by pressing ENTER after entering alpha entry mode.
I believe that the "*" symbol is intended to be the multiply symbol, which on the 42s is shown as an "x" (lower-case X) elevated one pixel.
As Tom said above, the "LF" is the line feed character, which is on the second page of the PUNC menu in alpha mode.
Hope this helps.
Jeff
