Alan:
In only the very most extreme situations where the highest performance is required for the absolutely lowest cost does it make sense to code in a way that puts a guard band around the A register. In by far and large the greatest number of cases it makes way more sense to treat the A register as a transient applied tool. This holds true to a particularly high degree when applied with the 8051 instruction set. With its powerful and richly capable registers and direct memory instructions there is even less incentive to "make A be one of your variables". If you consider the A register to be the spatula that flips the bytes instead of the bag that holds the burger then I believe you will find your coding productivity takes a big step in the positive direction.
