I am having to enter the program via my fx-9750GA plus so any saved keystrokes will help. obviously I dont really have the comments in the programming just for here.
Here is what I have so far:
[codebox]0->X
0->Y
0->B
0->C
0->D
0->F
"NEWTON"
Rad
"ENTER F(X)=0"
?->F
"ENTER DF"?->D
"GUESS"?->X
"APPROX.........DIFF"
Lbl 1
XB<printyarrowthingy>
'<comment> I want to print my initial guess X and the difference between my previous guess which would be zero on first round but this doesnt work
(X-(F/D))->Y
Y-X->B
'difference between new and old guess
Y->X
'Y is the new X
GoTo 1[/codebox]
I get 0 of course when I try to print XB because it is printing the product of XB not the values of X and then B: so I need the syntax for that.
I know the thing uses this method in the background but I need to be able to output the values for each iteration. Is there a better way to assign 0 to the variables other than one at a time. I know about the ~ for getting a range but what about my random selection of letters?
Thanks in advance

I tried
X:"........":B <displayarrow>
But that did not work - I did get the dots but no value for x or b?

Gave up on storing the equation as a variable that never seemed to work so now have to put the equations in f1 and f2....clunky but whatever works.
but would still like to concatenate the results...is there a way to do that? commas did not seem to work.
One more thing - is there a way to restrict the answer to 3 or 4 decimal places?
If anyone knows thanks
