QROOT Program creates Syntax Error

[MullenJohn]

Help.

I just inputted the QROOTS program into my HP Prime Calculator.

The Program QROOTS

EXPORT QROOTS(A,B,C)
BEGIN
LOCAL D;
PRINT();
HComplex:=1;
D:=B^2-4*A*C;
IF D≥0 THEN
PRINT("Roots are real.");
ELSE
PRINT("Roots are complex.");
END;
PRINT((-B+√D)/(2*A));
PRINT((-B-√D)/(2*A)); END;

This is the error message I am getting "Syntax error in program line 8"

Would you know why? I have tried degugging but to no avail.

Cheers!

I copied and pasted your program into both the virtual Prime and physical Prime (G2). It worked fine on both.

Thank you, Tom!
Could you consider why my HP Prime calculator gives the error message “Syntax error in program line 8”?
The line is ‘ PRINT (“Roots are real.”); ’
I am stumped.
Cheers!

It's hard to say. The line looks good and copying and pasting it works so I have no clue. You could try deleting it from your calculator and COPY and PASTE the code above like I did.

It appears the issue is the type of quotation mark used. Try "Roots are real." instead of “Roots are real.”, which should prevent the syntax error.

Thank you, Neek and Tom!
I used the quote marks under key [SHIFT] [9].
I changed to the quote marks under [ALPHA] [0], and it worked like a charm!
The syntax error is gone.
I couldn't have done it without your help.
Program works now.
Thank you for your insight on the quotation marks.
Cheers!
