Does that mean for the instruction set at 8052.com MOV B,A
would be something like MOV #iram,A. Whats the SFR? Status registers?

What I need to know is the opcode in hex for MOV B,A. I need the opcode for other MOV B,operand, but I can get by without them for now.

I don't recall any instructions for moving values out of the EPROM for in the instruction set. The MCU I have does have an EPROM, I beleive. How do you move values out the EPROM?

The kind of programs I expect to be putting on the MCU require evaluation of equautions like (( x1^2 +x2^2)-5*x1+x2/100)*delta t.
I've tryed to right algorithms to sort out the order of operations. First multiple to certain operands, etc. The algorithms/ functions do seem to work. But they are complicated. I fear that if I try to implement them into a 8052 they will have bugs in them. Is there any kind of subroutine that has been written for the 8052 that evaluates expresions with parentheses in them?
