[SOLVED] Given (|) in programming?
Hi, I am trying to make a program that calculates x intercepts. Right now, it can calculate the answer, but I can't make it restrict the domain.

I understand you can do this directly in the CAS app:
solve(SIN(x)=0,x)|{(x>-10) AND (x<10)}
{-3*pi, -2*pi, -pi, 0, pi, 2*pi, 3*pi}

But when I put that kind of syntax into my program, it returns "Error: Invalid input".

EXPORT XINT(expression,domainlow,domainhigh)
  LOCAL equation;
  LOCAL variable;
  LOCAL answer;
  answer:=CAS.solve(EVAL(equation),EVAL(variable))|{(EVAL(variable)>-10) AND (EVAL(variable)<10)};

Any ideas?
