1) Is there any way for me to have the calculator evalute an equation from assembler? maybe like a rom call or an exec_pg? 2) Is there an easy way to convert a string to a real? a rom call? 3) also one more question, I have a question about the Floating Point Stack. How do I know when the FPS is empty? thanks in advance for any answers. Keith Batten kbatten@usa.net
