help programming

[Arcturus314]

So I wrote a program that is giving me a syntax error:

EXPORT PROG1(A,B,C)
BEGIN
LOCAL D=0;
LOCAL E=0;
(-B+SQUAREROOT(B^2-4AC))/(2A)->D;
(-B-SQUAREROOT(B^2-4AC))/(2A)->E;
MSGBOX(D,E);
END;

squareroot is replaced by the square root symbol in the code
So what is the problem?
