Why the right(); command returns both sides of an expression? (SOLVED!)

[Spybot]

Hi Guys!!!

OK this is the way I found to solve my issue with the right(); command, from inside of a program, this command returns a list with both sides of the equation, all I did (after a long headache!) was taking the elements "Out of the list" that's it ... Done!.

Thanks to you Guys, I've been learning a lot about the Prime. here's the code... as simple as this:





EXPORT TEST()
BEGIN LOCAL M,B,BY;
INPUT({{M,[0]},{B,[0]}},"Title","m:","b:","Help");
BY:="y="+M+"*x+"+B+"";
BY:=CAS(BY);
BY:=CAS.right(BY);
PRINT();
PRINT("
Eqn. input by User:
"+exact(CAS("y="+M+"*x+"+B+""))+"
left side of the equation:
"+BY(1)+" //here is the trick.
right side of the equation:
"+BY(2)+" //here is the trick.

Thanks for Watching!");
END;
