How to compare values for equality by subtraction (SUBWF and STATUS Z) | PIC assembly programming

[@rhunllwyd9175]

Looking at bit 0 in the STATUS will tell you if the answer is negative or not. Great for checking if the values are greater or less than each other. A useful analogue input comparator.

Thank you for reminding me about mplab simulation. Now I need to set up counting 16 bit numbers in two 8 bit bytes and compare it in pic18f4431
